Selmer 100w PA guts. Unusual black face one.

Grabbed on ebay, didn’t seem to get much interest, but they are nice amps, I kinda have them pegged for the one that start shooting up in price along with Carlsbro when people realise they are the proper deal.



Standard massive choke in these, loads of power supply caps. All necessary stuff to beefy sound.


Tidy unmolested guts, clean too.


This is fun, apparently the amp is 100% efficient.


Croc skin Selmer Treble and Bass guts. Horrible state.

This came in because it has a bit of noise when used with a reverb.


Interesting caps, note that valve rectifier there.


Underneath, note that solid state rectifier there. Someone has disconnected that, and put it back to valve, but left everything else. Clearly toasted a valve which started a fire inside, but all the burnt wires have just been electrical taped. After hoovering it out, checked the fuses, and the ground, those are fine, so turned it on, since it was ‘working’ an I’m only looking for a noise. That bundle of wires caught fire. The noise was the shield on a wire on a preamp valve base touching the heater. This needs a proper rebuild.

Kelly 50w amp

These are always described as being a Selmer T&B badged differently. Finally I get to compare.


Guess its lost its back panel info, which might have given me a model name or something to work with, sleeve and chassis are similar to the T&B but the hardware, iron and suchlike are different style. Plus no heat shields. I tagged this as treble and bass, clicking the tag should bring up pics of previous ones.


Inside is very different, much neater work, different build style, different transformer means different rectifier (bridge rather than the full wave in thee mark 3 T&B). Circuit is similar sort of thing. Basically, they aren’t really comparable amps since the build quality is far apart, and having similar circuits meaning amps were the same would leave us with about 4 amps to choose from. Happily take a Kelly like this over any Selmer I’ve poked about it.

Ashdown Little Bastard and Selmer Treble and Bass Mk2 guts

Little Bastard works fine but opened it up for a look anyway:


PCB mount valves and pots, not ideal, but at least not all push connectors. Sounds great too, not really loud enough for my purposes. So for sale, £350.


Top view showing valves and iron. Did notice the edges of the chassis seams are not welded, seems solid enough anyway.

On to the selmer T&B.


Plenty of cobwebs and spiders going on, seem to predate the power valves by a fair bit, so someone did a bodgy job of them.


Underneath, looks like bias cap and resistor replaced. Compare to later ones, looks line minimal changes were made to add SS rectification, one had the diodes right on the transformer, other had a dedicated board.

Messed with Selmer Treble and Bass 100w guts


Fixer from ebay. Wasn’t expecting it to be so recently worked on. The new transformer was mentioned, but all new electros too. The notches filed into the front are to clear the bolts from the handle on teh sleeve. Because tilting it when you slide it out is too hard, apparently.


Pretty questionable work in here, especially replacing all of the filter caps with dual ones with only one half connected up. Soldering is a state too, and the resistors on the valve bases have to reason to have legs that long.

Here’s the worry though:


Nice burned up stuff. Scrubbed off the soot, redid the horrible wiring and replaced the diodes. Still blows its fuse, so might be the transformer gone. Those diodes aren’t actually connected to the cap, dry joint, which I think has done for it. On to the for spares or if a suitable tranny turns up pile. The replacement tranny in there is by Majestic Transformer Co who have quoted me about £160 for a new one. Not sure is worth it.

Klipp is working, on to the Selmer T&B

Fired up the Klipp with some tester valves after checking voltages were in all the right places, and it is good to go. Loaded it with new Shuguangs, very little noise, nice and clean, plenty of headroom. The Klipp circuit sounds pretty much like a fuzz/treble boost into a clean amp. Pretty happy with that. Case needs bits gluing back down, not something I’ve done before, will do a tutorial once I’ve nailed it.

Next one is the Selmer Treble and Bass 50 pictured previously with the awesome pot crust. At this stage, its just a boring clean up, paintbrush and hoover, spray the pots, the crust just brushed off. But here is a classic, actually the first time I’ve found it in an amp, although I’ve had a few with wired bridging the fuseholders:

The classic tinfoil. Kind of hoping that was just down to a bad valve, because I have no suitable caps in stock and would like this to be easy.
