MOSFET wasn't the problem. Still shut down with IRL530s. LM317 regulator replacement is next to try.
Had you replaced the heat sinks? And, just a thought, did you use "Arctic Silver" or equivanent between the regulators and the heat sinks?
Yes, I did miss post #30. I have been reviwing all posts of the V3 mods, and I saw the mod with the white LEDs (not your's and not recommend). Still waiting for final use of IRL510 or IRL530. Ordered a non-contact Laser thermometer for $11 and change from Amazon just for proof of temps. Cant wait to start modding my 2 units!
For Euf0ira, those are some impressive looking mods! Can you tell me what the Caps are in value? I saw the one valed 2200 mF. I also see you have wired some elements to a common point (ground?) . Has this improved the hum? Thanks...
My understanding is that the red an blue LEDs are part of the circuit. They are diodes after all.
Finished my V3 modding yesterday and must say that I'm very impressed! Switching to IRL510 made a huge difference in detail with silky-smooth crisp highs and together with photoflash cap for power and bigger output caps for the lower end I'm 100% satisfied and done modding this thing.
Since I'm still unable to post any pictures I'll share these links to the files showing the finished amp and a closeup of the heatsink with the moved components.
