Oh, left out some important stuff. I need muff circuit to combine with Tone Bender! Megalith is my number one pedal, hard to use anything else. I havent’t tried Hyperion.

TB+Muff combo pedal has been on my bench for too long. Tried BAT Revelation for muff circuit first, but didn’t pass signal. Next tried OK doomer and got it going for a while. Should I go trying IC muff next? Maybe Ionosphere?

500K pot with 500k resistor parallel between pot legs 1&3 could be a solution.

It isn’t safe and yes there is rules to follow. And there’s just plenty to know. First amp I modded did good for 6 months, but went dead after fail in bias circuit which caused tubes to run too hot. There was first heat damage followed by socket arcing on pcb caused by tube failure. The amp...

I resisted responding earlier, ’cos this whole conversation went downhill when bragging came in. Imma dumbity dumbee underachiever without ShATings, but I’d really like to hear a proper argument about this excessive tube wear happened by cold bias thingie. I’d be fine with selfmade description...

Next level DIY :oops:

Shouldn’t this state ”70% is used as max idle bias value for keeping under load operation within safe side”? Wasn’t even been born in tube era, but on what I’ve read so far the 70% isn’t ideal point, but just a maximum not to exceed and the actual ideal idle bias point varies from tube to tube...

Well this makes me to consider wanting a serious relationship with @Robert I’d feel so safe… …as a customer in a platonic tradership between a seller & a buyer. :ROFLMAO:

I’ve read some links you mentioned. Was it on EL34world or diyaudio where RG had a good conversation about the real purpose of extra fusing? But that was a good talk and lead me reconsidering and easen up with so called protective mods. After last years tube (+screen resistor) failure I’ve been...

Isn’t this not so good practice which could bring more harm as cathode is suddenly lifted with voltage on plate? Tubes are cheaper than transformers :p

That’s what I thought too, but pressing string over nut slot didn’t change the buzz nor making sure slot is filed to the right size. I’m leaning more towards faulty winded string with soon failing core.

I spend couple hours today figuring out why 5th string on my freshly fretworked Aria gives ringing overtones and sustainless note. Messed with bridge, insulated PU springs with shrinktube, adjusted and filed nut, adjusted PU height, tighened every screw and thought tuner might be the problem...

DONE. Didn’t except crowning to take as much time and force. Call it beginners luck, but this one plays so much better now.

Yeasterday night did overal leveling. Gonna continue with fretrocker and crowning.

Maybe rebranded 741? Found this from my stash, white knob underneath:

Yeah, better to be really prepared for SF rehousing. My rehouse has been sitting on WIP box for a year and half after loosing my intrest on non working circuit. Tried to use rotary switch with option for Fuzz1+Boost&Fuzz2+Boost, but couldn’t get it work. I really should just check every trace...

SF-300? I possess mod doc or a link, just need to dig it. Edit. jackpot, found it bookmarked. https://docs.google.com/document/u/0/d/1U_uanZZQ6463Fj_zyF2kRtD-brLEqN14gemASVcTgUA/mobilebasic?pli=1
