Thanks!

I've tried to find a schematic of the Dumble amp 183 and I'm not having much luck in my searches. Does anyone know where I can find a file of it? Thanks guys,

Thanks for the help guys!

I am puzzled. I am beginning to wire up my Dumble 124/4 6L6 clone and am working with the rectifier board. I have the same board as the attached photo and had some questions. The upper right corner has the two red AC wires to the diodes and a blue red wire to the bias circuit. Looking at the lower l...

I get one piece of useful information out of it though, if it is accurate, and that is that there were some problems with deteriorating solder connections under the silicone.

Someone even mentions Duane Eddy! Interesting opinions being expressed.

Thanks for the info guys.

I already have a 12"-V30 in a closed back cabinet, a 10" Weber California in an open back cabinet and an open back cabi...

M Fowler, thanks. I had open heart surgery 4 years ago to my mitral valve due to a congenital condition. Can I sue my parents for manufacturing a defective product ? :P I got the treadmill and ultra sound tests done on my heart last week and things turned out great. I'm in real good shape for being ...

Thanks for the info guys. I have a three day weekend starting today and assembling this amp will be my project. Got to go to the hardware store now for some nuts and bolts then a blood test. I have a metal mitral valve and get tested now and then for my coagulation levels. Anybody have non factory s...

Thanks RJ & rooster!

Thanks for the input guys. RJ, the OT has those exact colored wires. I bought this knowing it had two different output impedences but was not sure which was which. Out of curiosity is there a way of measuring the wiring with a DVM in order to figure out the impedance? I plan to use 6V6's with this b...

Thanks rooster!

I have a Heyboer OT that I plan to use for my second Expression. The primary side has 5 wires coming out. I've tried to look for info on the web for a multi-tap Heyboer but haven't hit pay dirt yet. Facts about the transformer: label on top "11415-1 9960746" red wire brown wire blue wire brown wire ...
