Problem solved. After tracing out the LDR, everything appeared to be correct that only left me to look at the fact that the voltage is higher than it should be in the SLO clone schematic. The Dual EQ notes for the switching circuit said to sub 47r and 33r with a pair of 15r's I guess due to the extr...

I have a Soldano SLO dual EQ clone and I get a very low volume output and I suspect the LDR layout is wrong and the LDR's are blocking the sound and sending the signal to ground. I took some voltage readings on the LED side to compare between channels and this is what I got in order of layout. LEAD ...

I have a ohm/voltage meter but no scope. I have a bypass front panel channel switch connected to switch without LED pedal. No change!! What do I look for on the dead vactrol?

I'm working on a SLO clone with dual EQ stack on a ampclones SLO100 PCB. I followed the BOM list and official SLOcone schematics. I've built many regular SLO clones before so this baffles me!! Overdrive channel works OK, all controls work. When I switch to Clean I only get a pop and faint sound at M...

I've been poking with a chopstick all day, also used a patch cable in the FX loop as suggested by a similar posting to check for corroded contacts. What puzzles me is what would cause the static once it is powered off from standby. Also the pre-amp stays the same and the gain is solid, so the issue ...

I have a 5150 that makes a lot of radio like static when you flip standby on to play. After 20 seconds or so the static fades away but occasionally comes and goes at a lower amount while playing. When you flip back to standby, the static comes back and fades away. When you turn off the power(while i...

Ok I just finished my SLO clone and my biggest problem was the Turret board layout was wrong showing the HV pre-amp to the wrong filter cap lead on the power supply. I was getting a very weird low voltage but the pre-amp still worked coming out of the FX SEND jack. So I fired up the amp and finally ...

I just finished 1 of 2 SLO builds and I cant get any sound whatsoever. I'm following the Turret layout floating around out there, I didn't wire Pin 1 & 8 on the power tubes for the Bias probe but instead together to ground like a Marshall. I made some mistakes with the Filter caps polarity but I hav...
