Post a pic of the solder side . I once soldered a resistor in a cap location and it produced a similar condition .

What LEDs do you use in these locations ? Water clear or diffused style ? And why green ??

J113 ... Any other optional units that might work in that location ??

Im starting to gather up all the components to build this compressor , and the BOM lists the BB OPA2134 op amp . I have two (2) LM4562 op amps on hand left over from a Carver C1 preamp revamp/restore . Would the the LM4562 Op amp work in this circuit ? Would it be a suitable replacement for the...

Update !! I was playing my Klon clone today with the TC1044SCPA that i had removed from the boost circuit mentioned above , and now i can hear the same faint wine coming through , so i know that it's these charge pump chips causing this issue . This Klon clone has been super quiet , and never...

Thanks to who all posted with the idea of the bad chip !! ?

Ok , So i pulled the 7660 from my Klon , and put it in the boost , and now the Boost runs dead quiet . Took the TC1044SCPA that i pulled from the Isosceles Boost put it in my KLon .... it runs quiet in the Klon ?? So i pulled the 7660 and tried the other 5 remaining TC1044SCPA ( That i have...

This last batch i got from Tayda , I've got some from them before without a problem and worked good . I'm gonna pull the 7660 from my Klon clone and see if that helps , the Clone is dead quiet !!

Yep , they sound fine as far as i can tell . I have a few modded Boss EQ's with them , and i can't tell the difference with the Tayda BB's .

Looking for any help with my latest build . Put it all together , and its got a crazy loud wine when engaged . By pass is clean and quiet . Using a known good Boss PSA120 power supply . Swapped out the TC1044SCPA with another one , no change . Swapped out the TLO71CP with another one , No...

Awesome rundown of each PCB !!! Thank you very much ! ??

There is 4 possible pcb's that contain the Freidman tone . Little Debbie Thermonic Dist. Brown Betty Dirty Sanchez Are they all the same , just different pcbs or what ? What one of these would have the most realistic cracked tube amp-like sound ? Style or lay out of the pcb makes no...

:)? Thanks again !!

So to recap ... Front left to right as seen on the PCB . E ------- C ---- B -----

These OC77 don't have a tab for orientation . They are only marked with a Red dot to show the collector . I just wasn't sure about the pcb etc . Nostradoomus Thx for your help . IMO , this should marked on the PCB as there are several transistors that can be used in that location with vastly...

Nice clean build !!! What enclosure ?

Can anyone tell me the pinout for the transistors in this build ? We are using pair of OC77 Mullard units with the red dots . The red dot = Collector on the transistor Base = center pin Emitter = other pin Q1 and Q2 As you look at the pcb diagram from left - right They are marked NKT275...

The Pedalpcb boards are not marked on the board with the standard 1 2 3 How are they orientated ? #2 Signal / Wiper is a given ... POTY70

Your input jack looks suspiciously close to the back cover ( When in place ) When you insert the cable the jack pushes the tang back possible touching the rear cover ? Does it pass audio with the rear cover off ? What are you using to isolate the PCB from the pots ?
