Vintage Tube Amp

Listing is for one. Heath Built EUA-19-4 Tube Amplifier Heathkit (NO Tubes). It’s in pretty good shape for the age. There are marks, scuffs, etc. Please look closely at pics for condition. Looks to be all original, except for the missing 12AX7 tubes. See my other listings/reach out for tubes if you’re interested. This is a HeathBuilt, same as HeathKit, but it’s factory built quality (not built by some electronics noob who probably can’t solder, sorry not sorry ;). There are scuffs, scratches, etc. Please see pics for the visual condition. As with any vintage item, please expect there to be wear, scuffs/scratches, odors, discoloration, rust, dust, signs of age, etc. Pics are of actual item(s). Item does not come with anything else, unless noted in description. If this is not acceptable, please send a note with your order, so we know not to upgrade. Please visit my store for more vintage items! Office reference: Item #25-1833.

Heathkit Model A-8A Tube Amplifier with 2 NOS 6L6GC Matching Tubes. Only the A-8A Amplifier and 2 additional Tubes come in this sale.

Console pulled The Fisher 460A vintage EL84 tube amplifier approx late 1950′s or early 1960s (See label and serial number in photos). This amp has been fully restored electronically w/ modern capacitors + modifications to account for fact that stereo tuner is no longer present in the console, thus a bias resistor modification is made to properly bias the tubes (See 20 watt gold power resistor mounted to underside chassis). All capacitors and components are top quality such as Nichicon electrolytic and classic “Orange Drop” coupling caps, etc. The original top-side “MULTI-CAN” large capacitors were left in-place for vintage aesthetics while all new capacitors for the DC tube supply voltages were built into the underside as shown in the photos. New rectifier diodes were also installed as shown. A thermistor was added to the A/C input side to soften start-up current surge to the tubes and also add slight voltage drop to account for higher line voltages in today’s homes. The tubes are (2) Sovtek EL84 + (2) Russian 6P14P (EL84) for the power output + (2) 7247 for input stage : The amp, since it hadn’t been run in a while was “burned in” on the bench for approx 2 hours and ran perfect. I re-checked the bias and supply voltages and everything was in-spec. No hum, no sound issues – it’s running great. I will include a marked-up schematic and an original un-marked schematic to show the modification(s) and resistor values performed and needed to make these Fisher console amps run properly in stand-alone mode as was done to this one. An ON/OFF power switch was added (it appears the green LED light in it is out, but does not affect the power switch function). There is also a custom mesh steel plate bottom w/ plastic feet that was added allowing proper ventilation to keep the tubes running cooler. The bottom plate is steel – I left it un-painted as a new owner may want to paint it a custom color or build a wood case for the amp etc and thus it shows a bit of light surface rust as it’s not coated at this point. This amplifier is intended for a vintage tube amp collector or similar who is fully aware of what they are looking at in the photos and how to safely handle a tube amplifier if they remove the bottom cover etc as dangerous voltages are present.

These parts are salvaged from a chassis. I tried to be careful removing tubes, but working condition unknown. I can’t guarantee the performance of these parts, but it was stored inside. I’m going to list chassis as well.

The product is a lot of vintage vacuum tubes, specifically designed for guitar amp and organ repair. The vacuum tubes are of military brand, adding to their unique and historical value. These tubes are essential components for maintaining the sound quality and functionality of vintage audio equipment, making them a valuable resource for musicians and audio enthusiasts looking to repair or restore classic instruments. Just so neat that a lot that I have found had been military grade in its usage.

This is a vintage Webster Chicago tube amp from late 1951 or early 1952. They have been successfully been converted into really cool guitar amps or harp amps, with very little modification. Drop the amp name into YouTube and you’ll see what I mean. I removed the maroon covering and the speaker grill years ago because it was looking rough. Hey I was 14, gimmie a break. Underneath it was this beautiful wood that you see in the pictures. This amp already has that vintage mojo, but a retro speaker cover would make it look incredible. The speaker does have a couple tiny tears (see pics). Some dummy took the speaker grill off ya know, so of course that was bound to happen. I glued one of the tears and it worked fine (I was using just the speaker with another amp), but those tears will need to be addressed, either with some speaker glue, a re cone, or a replacement speaker. I have always wanted to convert this over to a guitar amp, but I have to be realistic with myself and accept that it’s never going to happen, after all, it’s been sitting in my closet now for 40 years. Last time I tried to get some sound out of it, it kinda worked, but the volume pot was very scratchy. In preparing for this post, I did plug it in. As you can see in the pics, all of the tubes light up, so that tells me it’s probably just a couple of amp tech hours away from being the main topic of conversation down at your local blues bar gig. I see no swelling or leaking of the capacitors, which is pretty incredible considering this amp is all original. Original cord is in great shape, no cracking, and those sure look like the original tubes too. I recently bought a nice photocopy of the original 166 manual, and it includes the schematic. That of course comes with the amp too. Anyway, hopefully someone will see the potential of this thing. I sure do, but other priorities in life have taken over.
