Re: Quiescent noise barely heard in headphones, with speaker is pronounced

I do thank you for the reply. I'll have to do what I can to check the resistors, there's a flock of them in there but it's only a project.

Cheers!

Re: Quiescent noise barely heard in headphones, with speaker is pronounced

Thank you for that reply. Sunday I removed the head and used deoxit on all the pots and every electrical connection including the parallel connectors inside. The difference in the smoothness of the pots was remarkable, as expected, but there was no change in these noises. I removed both 6L6 tubes an...

Re: Quiescent noise barely heard in headphones, with speaker is pronounced

Hi Dom, Ugh, I posted this in the wrong forum. Apologies, my mistake, I meant to post it in the F-series forum. It's an F-50. There is a switch in the back to mute the speaker and the headphone jack is near-by. I know some of the Mesa line do not have this option, it's one of the reasons I chose thi...

A question for any techs that have come across this before. Any suggestions are very much appreciated. I hear a background noise from my amp which sounds like a crackly buzzing (not 60 Hz hum), which has frequent clicky somewhat loud bursts which are obvious in a quiet room. The audio appears perfec...

Some tube history about Mesa's 6L6GC STR454

I'm curious about the 6L6GC STR 454 tube series. I came into a set along with the amp and they sound really nice, much more full than the Electro Harmonix 6L6EH that came with the F-50. Not that the 6L6EH don't sound good, they do, I just like the STR 454 for the sound I'm looking for. I talked with...

F-50 tone & Speaker

Hi, my first post in the forum, so, hello. I've been an acoustic musician since 1970. I've learned the flatpicking style and most everything I've done over the years reflects that. Recently I decided to work on fingerpicking & bought a 2017 remake of Chet Atkins 1959 Gretsch with TV Jones Classic Hu...
