Vintage Tube Amp

Bogen Challenger CHS-100 Tube-Powered PA Amplifier Vintage Untested – Powers On. When plugged in this powers on (a light appears) but untested further.

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.

Estate item AS-IS untested. Missing the main speaker driver, back cover and spindle legs. For parts or repair. This would make a really cool guitar amp box.

Grundig standalone console speaker. Powered, with internal tube amp, power switch, and tone controls. I did not plug it in or attempt to test in any way, tubes are not my area of expertise and I did not want to risk damage. Appears to be complete and original. I don’t know the model name. Google searching indicates it may be a V-Box II? It is similar to some non-amplified Grundigs and stylistically similar to some of the Majestic models. 31″ tall, 21.5″ wide, and 10.5 deep. Cosmetic condition is very good. There are small chips here and there, some minor marks and scratches. The laquer coating on the top has some cracking, it was hard to photograph. It’s a very thick coating. There is a small ding in the trim near the bottom. The grill cloth is stained. Legs are screw in type, and are sturdy. If you need to see additional details or have questions please let me know. Will be expertly packed, these are rare, hard to find, and I don’t want it to get damaged any more that you do.
