PSU testing
#1
Hey folks,

So I've built my first London Power standalone preamp kit and unsurprisingly it doesn't work. This is my first amp project; I'm used to building pedals. But I have to start somewhere. It's the M-Pre (hot rodded 800 version) with the Pre-PSU for two tubes.

So what I did was build it like I build a pedal. Basically followed the instructions, put it together and turned it on. Of course in hindsight I should hve been constantly testing as I went, but as i said, it's my first one.

So the tubes didn't come on and of course there's no sound. So what should I do first? Check the psu, I guess. So what would be the best way to go about that. I have some basic electrical knowledge (mostly safety stuff) and of course a dmm. Any advice would be greatly appreciated.

Cheers

Steve
