I am now joining the can't hear a difference between OP07 and LM308 club :LOL: In other news with my rat, I do really like the turbo style clipping though. Glad to have a switch between silicon diodes, LEDs and neither (just opamp)

Source image inspiration :LOL:

Not sure if this is a faux pas in the build report forum to not have many words. Figured I would share a few pictures since I have never shared anything here before :) First tayda UV print came out nice, I am happy! I don't wire them for gut shots unfortunately :LOL: Full board...

Found one local to me and grabbed it, it was not genuine, nice I think I will just give up on this and stick with the op07 for my own sanity :LOL:

Yea mine was in a General Tso compressor so it was very noticable/important for me to get right due to it's role. Totally agree with @Chuck D. Bones on it's use in this application!

I also just experienced an issue with one from tayda, not sure where you sourced yours from. The issue with mine wasn't a warmness it was straight up noise and distortion/overloading/clipping/different behavior when it should not have been due to different specs on whatever chip it actually was...

Do I really want to find a legit lm308...hmm... You guys almost convinced me... I doubt I will hear a difference but also have a sick curiosity

Fun stuff then, I put a socket for the compensator cap in case I end up with an lm308, I also changed the 4.7uf C2 cap to 2.2uf and it sounds fine 🤷‍♂️ I couldn't really find any confirmation anywhere that what I was experiencing/hearing was normal, so I am glad you both say it is! It was my...

I recently built a stock rat and think this might be what I am experiencing/want to look into With the distortion anywhere above ~10-11oclock, any amount of power chords or E/drop D string, really starts to sound a bit flubby and overcompressed or overloaded. I have high output pickups and can...

Opamp technology and usage has changed too much in the past year, you would need to start over? /s

@Chuck D. Bones Can you summarize for me what the chargepump is actually offering/bringing to the Greengage (plumes) circuit (all non-inverting)? Most charge pump circuits/rationale I can find is related to bringing the voltage/gnd to 18v/0v for the opamp Vcc/Gnd, but in this circuit it is...

Don't buy all of the sludgehammer pcbs when they come back in stock 🥺, I have been waiting a month or two with components in hand ready for it! I want to replace my BDI21 :)

New OPA2134 from mouser came today Popped it in and the sound I was hearing is gone, General Tso is perfect now. I performed the same test with the unity gain setup and got 8.48mA so basically exactly matching the datasheet (vs the 0.96mA I got for whatever the Tayda chip is/was) Top is fake...

This thread was helpful to me. I just finished my General Tso build and have some strange behavior/noise that I was debugging. This lead me down to considering the OPA2134 I got from Tayda as a culprit. The photo shows a pretty poor looking BB logo (regular font?) and a missing pin 1 indent...
