Re: JTM45 with the twist...
No this is my first amp... but I've heard some others and even a D style amp as well.
Nothing wrong with it.... it takes a bit more room, but it's lighter and it sounds great.
Here's the final picture of the amp...

Re: JTM45 with the twist...
I used 4mm thick rubber pads on both sides.... it should be OK but I guess time will tell.

Re: My SSS 001 As Built, Corrected Schematics
This is grate Markus, thanks... I did measure RMS voltages with my scope, with different filter values and my measured voltages reflect exactly what you posted here. I think I measured everything at 500Hz, 1kHz, 3kHz and 6kHz Which SW did you use for this.... I think I need to have it. :wink: BTW do...

Re: My SSS 001 As Built, Corrected Schematics
150k resistor to the Hi switch definitely doesn't work... I tried several different values and I think I will end up somewhere between 10k and 20k. When I left the amp I had 15k in there but that might change, after I play the amp a bit more. I also changed first cap from 100p to 20p... there is alm...

Re: My SSS 001 As Built, Corrected Schematics
Just for the recored - #001 and #002 are basically the same amp with the exception that #001 has the Tremolo and #002 does not. Mixer circuit, filters, power amp etc... are all the same as are the layouts. Bill www.sebagosound.com If that's really the case then this schematic which we have here is ...

Re: My SSS 001 As Built, Corrected Schematics
Looking at the filter schematic on the first page of this post, that 150k in series with the capacitors to ground would seem to block any effect those caps would have on the signal... You could try removing that resistor and see what happens... I've used the 002 filter version and it works well, at...

Re: My SSS 001 As Built, Corrected Schematics
OK just have to share a few things about the amp... ...the amp sounds awesome. I think I never played an amp which sounds so tight and precise but still with a lot of content.... can't find any better words for it. However I have to report that Hi filter doesn't do much... at least on my amp. I chec...

Re: Oscilloscope coming soon - please help!
Thanks for that, :D so I would need a dedicated function generator which supplies a voltage and a test signal rather than just audio files of test tones? I strongly suggest you invest in some function generator... it doesn't have to be something fancy. Ebay is full of them... or you can get somethi...

Re: Oscilloscope coming soon - please help!
I have one doc where you can find explanation how to measure Output Power of the amp using a scope.
It's not much, but it's a start.
