Title: homebuild jtm 45 high treble channel
Post by: maartenc on March 02, 2015, 06:19:04 am

Hello everybody,
i build myself a jtm 45 clone, and it works absolutely fantastic.
the only problem i have is it has some hum on the high treble channel.. i can still play it though, it's not ruining the complete amp,
but when i switch to the normal channel, it is dead silent unless when i play or crank it up all the way...
any ideas anyone?

Greetz

I guess you could say it's more of a hiss kind of a sound... so it's normal for the high treble channel...
