No inside pics yet, but here's my dual 2U 1176 using Jakob's boards... I'm still working out a possible power supply issue, since I used 22V toroid it can be around 24 ~ 27 VAC depending on how good the power source is. Any suggestions of how I could fix this without having to get a new toroid? I have another 22V around, but rather not use 2 toroids.

I was curious too - I copied Gyraf's labels, the ratios are labeled 1:4,1:8, etc - shouldn't they be 4:1, 8:1, etc?

I'm matching FETs and just hooking up #7 (stereo interconnect on schematic) of both boards to the toggle switch. Haven't actually tried it yet, I wanted to calibrate both channels first. I got a whole bag of BC107's from Ace Electronics in San Jose, CA so I just have to test em out.

Thems mmmmm-good. Like the panel graphics =)

Maybe my next pair I'll do this way.

Hello KDAWG,


Would love to see some inside pics of this. Would you be willing
to share your Front panel express layout? It is a nice layout!

I thought about this as well, anyone try this yet?
What kind of potentiometer would you need? Dual Cocentric? (sp)

:cool:
