Vintage Tube Amp

Looks like a 1950s amp chassis with 2x 6L6G specified for the output tubes; two different rectifier tubes (5Y3, 5V4-G) and a 6SN7-GT as preamplification or driver. A good number of transformers and chokes here – take a close look at the part numbers and codes and you might be able to cross-reference some older gear US military? That would help identify this piece. The chassis measures approx. 16″ x 7″ x 3. Weighs about 23.7 lbs. Thank you for looking!

THIS COMES AS PICTURED. I WOULD GUESS IT NEEDS THE WAX AND PAPER CAPS REPLACED AT LEAST JUST TO BE SAFE. IT WILL COME WITH ALL THE TUBES SHOWN. ALL OTHERS TO USE EIS.

Vintage early Black UTC LS-55 Audio Output Transformer for 300B or 6L6 tube amp. Used but in good working condition, tested no open coils.

For sale is a vintage General Radio Co. Model 814-A serial no. This vintage piece of test equipment was produced around 1937 for lab use. It has three mixed brand type 34 vacuum tubes. This piece is in decent condition for its age with many signs of wear and age. The gain knob had a piece about 1-1/4 wide broken out of the base when I acquired it. Luckily, the missing piece was inside, and I was able to glue it back together. The cracks are just faintly visible on the front (see photos). There are a couple small holes in the front right above model/serial numbers. I’m not sure if there is a badge missing or these holes were for. Otherwise, this piece appears to be complete. Nothing is obviously missing or altered. The cabinet is intact but most of the original finish has worn off. The underside of the top appears to have some staining from moisture. This staining from moisture damage covers about half of the paper schematic/instructions. The cabinet is just slightly loose at the bottom left corner joint (see last photo). Electronically, this piece appears to be pretty clean and in good condition. This piece originally operated on batteries. Please see all photos for condition and completeness of the item. I can provide additional photos upon request. Cabinet dimensions are 12-1/4″ wide (excluding handles) x 12″ deep x 8 tall.

Up for grabs here is a very rare pair of 12AX7 new Old stock tubes both in the original boxes. I believe both of these tubes are TUNG – SOL rebrand tubes. This is a blue printing pair of tubes. One of the tubes has smooth black plates and an angled square getter. I tested it and it tested well with the new Old stock values. It was at like 990 on both lines, whereas a typical new Old stock tube averages 1000 so it is well within the average ranges. The other Tube has grey plates and a goal post getter with a foil strip with twin dimples in the foil strip at the tip. This tube also tested new old stock at 990 on both lines. I did a bit of research on these tubes and I believe they’re both manufactured by TUNG – SOL. Feel free to ask any questions you have order to make an offer. Thank you for looking. Have a blessed day.
