Anyone own a Concert Bass? (red logo)
« on: December 15, 2003, 05:04:13 pm »
I can't get this thing working, and I know there are several crossed wires on the power amp board.

Can anyone send me a photo or diagram or anything of the power amp board?  It would literally save me countless hours and headaches trying to track down all the problems this thing could have...

e-mail me at cswiney@inet99.net

I made a diagram of connections in this amp in paint.



Can anyone let me know if any of these wires are crossed as suspected?  Or if wires are on the wrong posts, anything like that.

I'll try to take a picture for you, but I don't know if it will come out detailed enough to help.  No promises, I'm pretty busy, but I'll try.

Mine is a 75 model.  It works, just needs new filter caps and a new volume pot....

You come through for me and I'll name my firstborn after you!

I haven't forgotten about your amp pic!  I've been pretty occupied, maybe this weekend I can get down in the basement and dig out the amp for you.

Can anyone check my diagram against their working model?

At this point, I'd send $5 or $10 cash to anyone who can just hook me up with a good picture of the wiring connections on the power amp board and preamp board.

I love and miss my sunn, someone have pity!

I've searched high and low on the internet.... all to no avail!
I've offered money just for a good picture.... with no luck!

I can't find another concert bass around here, as I am currently stuck in Kentucky, so I can't find local help.  You guys are my last hope.

I switched ISPs, so the previous e-mail addy no longer works, but I check this page almost daily, so anyone who can help just leave it here.

I bought a Behringer replacement head that I use now, but it just doesn't have the tone of my old Sunn and I miss the poor thing.

Someone please take pity on me!
