Ashdown ABM Evo III guts

Not my usual, but Ashdowns tend to be fairly easy fixes, stuff is accessible, and the tech support is good it it gets hard.

Buncha replaced knobs, it has had a life. Nasty loud buzz that doesn’t stop when you turn the output volume, but kinda cuts in and out when you wiggle it. Valve is an EHX, tests OK.

Power board pulls easy, few screws, resolder the power caps. EQ controls have their own board, just undoing the pots and taking the tips off the sliders gets that out on some wires. Replaced the master vol pot as had one in stock, that fixed the noise, but intermittent volume changes when prodding the board, so not the only issue. Everything else off the front and more screws to get the rest of the pre board out, balance pot is bust out the solder, solder that and everything else that is a getting loose risk. Back together, and it works fine, but the dial does light up any more. Arse.

Ashdown Peacemaker 50 guts.

think I’ve blogged a buncha these, but they remain kinda stealth Matamps. This is a 50w with the aluminium knobs I’ve not had before. The knobs are much fancier in person, look kinda tacky in photos, machined aluminium to touch.

Matamp turret track build.

Unpopulated valve bases. 100w PT topside too, so probably built mostly and finished as 50 or 100w to order.

Loaded with 6550, sounds great with bass, so I left it like that, bunch of the JJ pres were dead/microphonic. For sale, £400.

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.

DSCF1460

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.

DSCF1464

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.
