Hi All, I've got two Ampegs - A B2RE solid state and an old SVP PRO preamp. I'd like to use the SVP as my main pre (for obvious reasons) and use the B2RE as a slave amp. I'm currently going from a preamp OUT (1/4" socket) on the SVP to the poweramp IN (1/4") on the back of the B2RE, I know this shouldn't be rocket science, but the pre is really noisy when connected like this.
When I use it at home or studios (it's my main recording kit) it's practically noiseless. I'd like it to be noiseless live too, but so far that luxury has escaped me. It's been retubed with quality tubes, and had new power supply caps and a new mains transformer fitted (both from authorised Ampeg suppliers), and the fact that it's quiet when it's just being used as a pre leads me to believe that the problem isn't wit the SVP.
Any thoughts? Does it make a difference twisting the two wires that go from the AC inlet socket to the On/Off switch together to act as a 'choke' (of sorts)? is this even safe?
[b]edit:[/b] I should add that everything is coming from the same 13A ring - heads, pedalboard supplies etc..
