Modern radio equipment always works whenever you turn it on.  There is little challenge or reward in it.  I'm an engineer and a big fan of early radio technology.  There's still some sort of magic in them!  Alas, my collection is in a limited space, so I have listed some of my sets here to make room for others I have acquired.  I tend toward high quality radios.  They are the most evocative and the best investment.

Loose Coupler (Electro-Importing or Signal Electric)

NEW!

Loose Coupler (Electro-Importing or Signal Electric)

Here is an especially nice example of an early Navy style loose coupler. It was sold to me as an Electro-Importing Co. of NYC unit, but I have been told by one person it is from Signal Electric Co. of Menominee, Michigan. Either way it is especially nice with a beautiful original finish! Nicer than most!  $225.00. (1160049)

 

Early Radio Spark Transmitting Coil

Early Radio Spark Transmitting Coil

Large and powerful early radio spark transmitting coil. It works great and very well made! It has triple contacts on the primary side and is very reliable as a result. The brass mechanisms for adjusting the vibrator speed and tension are beautifully made!  $600.00. (1160045)

 

RCA IP-501A Receiver

NEW!

RCA IP-501A Receiver

The IP-501A is the last in a line of development of radio receivers from the Navy Bureau of Steam Engineering. RCA kept making them well into the 1920s. They were considered the pinnacle of receiver design for a long time. They have a switch on the panel allowing you to use the built-in detector tube or an external crystal. It also has two built-in audio amplifier tubes. The cabinet has two shielded compartments to ensure selectivity. There is also a buzzer to act as a local signal to find the sweet spot on the crystal when using as a crystal set. This set has a nice front panel and cabinet, and the wiring is pretty much intact save for replaced transformers and one loose wire. It should be easy to put back original. That's a big deal because hams modified many of these! The dials and nickel show normal wear for their age. The oak cabinet has its original finish! The original tube socket assembly is intact! This one is a pretty nice example and at an especially good price! It will be packed in foam rubber for protection.  $2,350.00. (1160048)

 

Federal 200 Regenerative Receiver

Federal 200 Regenerative Receiver

Nice and rare Federal receiver. The receiver is in unusually nice original condition! The front panel is just great. All parts are there including the transformers which are buried under a spring loaded cover. This model was designed to take either the 01-A tube or a big Western Electric tube as the final audio output! That is why the last tube hole is so large.  $350.00. (1160042)

 

Antique Galvanometer

Antique Galvanometer

Antique galvanometer similar to that used by Marconi with his early coherer receivers circa 1800. It is in excellent condition with nice original finish and is working perfectly! Scarce!  $200.00. (1160043)

 

Jewell Tube Tester Radio Test Set

Jewell Tube Tester Radio Test Set

Nice vintage Jewell radio test set and tube tester. Looks to be pretty complete in original leather case. Interestingly you can test the tube as it perform in the radio's circuit. It has a plug that plugs into the tube socket in the radio. You then plug the tube into the tester and analyze it as it is performing in the radio's circuit! I have not tested it as I don't have a manual instructing its use.  $50.00. (1160046)

 

Marconi Era Key - English

Marconi Era Key - English

I can't find any maker's mark but the base of the pivot is tapered as Marconi keys were. It is in unrestored condition with patina intact. There is some surface corrosion as shown. One knurled cap may be missing - I'm not sure. I've not seen another like it.  $135.00. (1160031)

 

ERLA Superflex Receiver

NEW!

ERLA Superflex Receiver

Here is a rare ERLA Superflex radio receiver in nice condition! The name Superflex suggests it is a reflex type receiver in which the tubes are used for both RF and audio. Such sets tend to give better volume than regular type regenerative sets. I noticed a couple loose wires inside. The ERLA sets were better sets in general and highly regarded.  $215.00. (1160050)

 

Kennedy 110 Receiver

Kennedy 110 Receiver

Very nice and rare Kennedy receiver. This early regenerative set was so highly regarded that people were still using them in the late 1920s! It is beautifully made with bank wound coils, silver plated dials and a solid mahogany case. With an Arbee III power supply or the proper batteries, the 110 can pick up AM broadcast stations from pretty far away. They also tune down to 12 kHz! No that's not a typo. You'll need a 100 ft or so long wire antenna for AM broadcast and a detector tube (200A works best). It is quite original save one knob which is very close to correct. The two knurled lid catch screws are proper reproductions. All else in excellent and original, even to the intact seller's label under the lid! This is a nice unmolested set with original finish.  $1,250.00. (1160047)

 

Spark Gap with Marconi Patent Label

Spark Gap with Marconi Patent Label

Nice early spark gap with porcelain base and long zinc contacts. The base has labels underneath. One of them cites a Marconi patent as shown. Early item!  $160.00. (1160041)

 

1800s Wimshurst Spark Generator

NEW!

1800s Wimshurst Spark Generator

The photos tell it all. This is a spectacular Wimshurst generator from the 1800s. It measures 40" long! It has a beautiful tiger stripe oak cabinet with superb fittings. A large salt container is shown for size comparison. These were used to make large and powerful static electricity sparks. From the length of the sliding brass rod this one should make big sparks! It was used for electricity research before radio was invented. Nothing is broken though one disk is a bit loose and the nut needs tightening. I won't ship due to all the glass but am happy to hold it for pick up for several months if needed. You won't find another like this! Very impressive in person!  $1,500.00. (1160051)

My Restoration Philosophy

Pre-1930 sets: I don't do any thing to harm the value or destroy the history.  For pre-1930 sets this means not replacing components unless they are absolutely the exact correct ones.  Unless the finish is horrible, I will simply use color matched wax on the cabinet.  I'd rather restore too little and let the buyer do more if desired.  It's very hard to go the other way.  I think that time and values will support this approach as sets get older and more historic.

1930+ sets: For later sets, I will replace old electrolytic capacitors and wax paper capacitors that are bad.  Contrary to common belief, most wax paper capacitors 0.1 uF and smaller are fine unless they have gotten hot and the wax has melted.  I test them and replace the bad ones and leave the others alone.  I will replace all black beauty capacitors as they are little time bombs.  I generally try not to replace other components unless the radio is not working properly or the components are in a bad way.  I leave the original workmanship in place as much as possible.  I will clean contact with Deoxit if necessary and remove dirt and grime without harsh chemicals.

Descriptions

I generally buy high end radios and I don't go for ones that are in bad shape.  I try to describe condition accurately so you have no surprises.  However, if you are an expert in a particular radio that I am selling, you may spot details I do not.  If you know of certain things to look for with a set, please ask and I'll be happy to try to find out and also to learn something I did not know.  If you are very particular about certain features or condition issues, please ask.  My goal is to remove any discrepancy in expectation up front.  If I have tried a set, I'll tell you what I observed.  If I have not tried it, the listing will not include any information on that.

Packing & Shipping

I pack better than just about anybody.  I have shipped radios weighing 110 lbs, with no damage.  That means using big boxes, with the proper foam and padding and handle locations and caution labels.  Most importantly, it means using the right shipper! I will not use UPS, ever! FedEx Ground is recommended and mandatory for anything over 25 lbs shipped in the US.  I will also use US Postal Service for items under 25 lbs if desired.  I do not mark up shipping materials one cent.  I charge no packing labor fee at all.  What I pay, you pay.  Radios will be shipped fully insured and fully declared for customs.  Please do not ask to do otherwise.  I pack assuming the radio may be dropped from 5 feet on a corner.  This generally means packing can be expensive for big sets.  Skimping on packing is a false economy.  I won't do it. 

Of course, the buyer may pick up a radio from me at no charge.  I can hold a radio for a while until that is convenient.  The smaller the radio, the longer I can hold it for you.  However, we must agree on a maximum storage time as I can't keep it forever.

Payment

Once you notify me by e-mail you wish to buy a radio, I will e-mail you and invoice to be signed and returned to me.  I will hold the radio for 7 days or until payment is received, whichever comes first.  Include the invoice with your payment.  Payment must be received within 7 days of your e-mail notifying me of your intent to buy, or it will be released for sale.  Multiple requests to buy a radio will be handled according to dates of e-mail notifications of intent to buy.  I will accept the following forms of payment: USPS postal money order; US money order; personal check (delay for clearing); cashier's check; cash.  I don't accept electronic transfers or Western Union transfers.

Terms of Sale

I try to describe radios accurately, even a bit harshly.  However, a buyer may return the radio (ship date) back to me within 4 business days of receiving it.  You must contact me before returning it.  It must be returned as packed, so UNPACK CAREFULLY & KEEP THE PACKING MATERIALS.  If the radio is returned to me in the same condition as sent and it is the same radio, I will happily refund the purchase price of the radio.  I will not otherwise.  You are responsible for return shipping cost.  If it arrives damaged because you did not use the same packing or returned it by UPS for example, I will not refund it.  You have as much responsibility to get it to me safely as I took to get it to you.  It is only fair.
