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.
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.
There should be a stuff for sale link that has links to things I have for sale in such a format that they are up to date even when I forget all about this blog. Check them out and let me know if it works right.
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.
Laney VH100R, made a bunch of noises and blew a fuse.
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.
