Re: Low volume issue
Pre amp is fine running through other amp. Problem is in the power stage. I'll recheck my connections. And test some more. Thanks for helping me narrow it down.

Re: Low volume issue
I have another working build, could I hook the "pre amp out " from that to the power amp input of my defunct amp for testing purposes?
I don't have a scope anymore, but I agree this might be best diagnosed with one. I'll double check my connections too. Thanks

Low volume issue
I'm having a strange issue with low volume in a 183 d style build and was hoping someone might have some insight. Basically all my controls work as they should but the volume level at Max volume is low, like 2-3 in loudness. Channels switch, and the issue is the same wether in clean or drive. Tried ...

Re: Starting point for new build
I made a 183 clone using high voltage music man transformers and think the HB's sound the best but I have been also liking playing my SC tele through it. Wasnt #124 voiced for single coils?

Re: Building the Dumble Amp?
You should try searching, there is a thread where some of the more notable builders describe their build sequence, I think funkalicious groove, henry, and glassman, among others, are in that thread.

Re: 100w ods
They are marked to show the polarity of the cap, although some are marked on two sides because I measured the caps once with a meter/foil and marked them, then read a blurb on the Aiken site about using a scope so I tried that and some of the results were different so I wound up marking them again. ...

Re: 100w ods
470ohms, yes, sorry. I do not wish to accomplish anything in particular, just have it sound the best that it can and be "right". There are some that say there is no audible difference between 1K and 470, and others who say there certainly is. In the end Ill have to try for myself because In the end ...
