Laney TT100H guts

Not come across these much, rarely mentioned. Fairly big fan of the GH series, and the VH100R, figured this is a more fiddly, MIDI enabled variation.

Too many knobs and buttons

DSCF3141

Stacked PCBs, board mounted pres, power valves wired up oldschool though, different layout to most Laneys.

DSCF3144

Top side, pres pulled, all JJs and all super loose inisde, causing various issues. JJ have not been doing great of late.

This amp is for sale, £300.

Ashdown LB550 Little Bastard Class D hybrid head guts.

Totally forgot to take a pic of the front, but not a hard one to track down. Hiwattish preamp by Dave Green, coupled with a ICE power module by Bang and Olufsen. Took apart as cut out at a gig.

DSCF3101

Not sure of the function of topside PCB. Seems a complete pre undernneath and the power module is its own thing. Important thing noted in this pic is ECC82 in the inner position. I totally forgot previous time I whipped the valves out of one, seemed to work happy with an ECC83 in there though.

Wilsic 100w two channel head

Styling in between the previous Wilsic and Miles Platting amps I’ve had. Apparently a fairly early model.

DSCF3266

Poor cap job. Just rattling about loose on the wires.

DSCF3268

Guts, not as tidy as previous one, but more stuff has been done in here. Not sure if snubbers on the rectifier actually does anything in the audible range.

Matamp Quasar 500 and Laney VH100R guts

DSCF3367

Showed up set to bridge mode, had to open it and find the switch. Turns out not on the side with the diagram. Do spot a toasty looking resistor bottom left though. Still tested right, luckily as it was missing a stripe.

Right side this time, showing the classic K135 and J50 mosfets. Hand marked bridge/stereo switch on the pcb to the left.

Other thing:

DSCF3357

Laney VH100R, made a bunch of noises and blew a fuse.

DSCF3360

A shorted power valve, a miles out of spec (like, measured a couple of meg rather than open) grid resistor. Suspect someone tried a ‘fix’ by swapping positions before selling this as ‘working’. Couple of dud pres too.
