Q & A / Beta Lead 'both inputs' -> No Sound / No LEDs
« Last post by marvin on March 27, 2018, 03:11:44 pm »
Hi folks,

first of all I am new to Sunn amps, but I had the chance to get myself a cheap beta lead combo, so I took it without thinking twice or testing the amp.
Both channels and their LEDs work fine separately, but when I use the 'both inputs' jack, there is no sound and both LEDs are off.
However, when I use a second cable to connect the channel A and channel B jacks, the channels are combined, both LEDs are on and everything (sound, knobs) works as expected.
But thats not how it is supposed to work, right?  :?

I used some contact spray on the input jacks, but that does not seem to solve the problem.  :-D

Any ideas, what might be the problem here? Thanks  :-)

Unpacking, I ran across a vintage SUNN catalog from 1969.

Enjoy!

Q & A / Re: Beta Lead A channel barely works but B channel works great..

Loudthud,

Just tried that and the A channel sounded the same, but Iím still going to try some cleaner.

Evilroot,

Yes Iím ok with opening the amp up. There is rumor of a guy that lives here that used to work in Portland building PAís. Iíll try and track him down. What do you think I should tell him to look at?

Thanks you two for the quick response. Internet is hard to come by up here.

Geoff Daking was the drummer. He operates Daking Audio now. You could probably ask him some questions. He's a real gear head.

I recall a tale from a friend about coming across a garage sale where some f this gear was offered.

I emailed him to refresh my memory.

The Who also borrowed the Blues Magoos backline while touring with them and Herman's Hermits in'67. Additionally, they were likely the same amps used to record I can See For Miles:
