Thank you! I have changed that now.

Thank you Martin! I will try to lower the V1 plates as you suggest and also change the GNFB to 8 ohms. Will it be the same even if I install a jack for extension speaker? Thank you Romberg! Yes it took a while to do it, but now it's done :D As you wrote a year ago it was the planning and adjusting t...

So now it’s finally up an running! It started without any problem at first time and sounds wonderful with no hiss or hum so far. I have done some edits to my previous layout and there are still some values to tweek, but right now I just think I play it and learn how it feels. As I wrote in my earlie...

After a long time with no progression I've now made a layout for my Fender Super60 amp. It's based on the #124 schematic but with no FET-board and no rock/jazz switch. I also did the layout for tradiotional Fender tone control but with a 100k mid pot so I can get a bit of the PAB sound and try the D...

Thanks for your replies and advises! Yes you might be right that I worry too much about signal line and the heater wire. In the end the layout and placement of everything seems to work in the Super 60 anyway. First I must say I was a little bit unclear. My amp is more of a D'Lite type amp with no FE...

Hi! I have a long time project converting a Fender Super 60 to something else. Right now it's like a Rob Robinette's Black Vibe where I used the left over preamp tube to add a cascading Dumble drive stage. All is done on the original pcb and some components are soldered on the potentiometers. It wor...

Thank you!
I see if I get some more answers before I try that. I have some buffers but no reverb pedal.

Thank you. My intension was, if possibly, to tweak the ic-driven reverb circuit thats on the Super60's pcb. I've read that somebody have done that with the HRD ciruit which is almost the same as in the Super60 but with some differente values. The tank is from the Super60 so it's impedance is not for...

Has anyone tried to use the Fender Hot Rod Deluxe reverb/loop in an ODS-build? I have translated a Fender Super60 to an ODS#124 style amp on the original pcb. Then there already are a similar reverb and loop circuit as on the HRD that I have tried to use, but I can't get it to work ok. I think the s...

Thank you!

Then it's worth to give it a try to see what I can do with it.
