β22 Rehoming

Postby Salmonkid » October 7th, 2019, 4:24 am

Hi all,
I've had a beta22 for a number of years now, but decided to rehome it in a set of parmetal cases with new panels from front panel express, to match the gamma 3 build I was getting close to finishing.
I also had a weird ground loop problem, which seems to be resolved now just from redoing the wiring - the leads going in to the stepped attenuator (and also the headphone jack) were a bit brittle, and i'd get what sounded like a ground loop every 4-5 minutes which only went away if I touched the case.

I've got it set up with 2x gain, 30v Sigma 22, goldpoint stepped attenuator, 3x input selector, and an epsilon 12 for power on/off muting and dc offset protection.

I've still got a little bit of work to go - bit of wiring to clean up in the PSU, and 2 more inputs to wire up (got impatient, wanted to listen again)
