If anyone with a MK VI can answer a question I would really appreciate it.

Does the knob on the front control the amp gain, or does it attenuate the signal? If the latter, does it do this to the input or output? Anyone know the specs on the pot?

Thanks very much!

Basically ALL amps attenuate the signal on the input.

RSA has some that do it between gain and output stages, but that is very rare by design.

I see. So its almost certainly an attenuator.

Thing is I have a DACT 50k balanced attenuator from an old, dead project just sitting in a box. I'm wondering if it could be used on the MK VI and if so, would be a worthwhile upgrade?

Not sure what pots in there and exactly what it does.

It is not "almost", but certainly an attenuator. Whatever gave you the impression it would be dynamic gain control? That whole principle is a VERY bad idea as amps act differently at different gain and changing the gain while it's powered on is generally undesirable.

Think that DACT will fit?

I guess I kinda wondered about it from setting all of the different amp's gains that I own...

Hard to tell from that pic if it will fit. I can't tell how high the fuse assembly is that sits behind it. Here's a pic of my attenuator.

At this point, since you have both in your possession; just open it up and check

Ah, if only it were that simple. The Mk VI is somewhere over the pacific right now and I have someone that wants to buy the Dact unit.

Would it matter much that this attenuator is 50k? I've seen pots used that were 100k.

 

[FallenAngel]

Shouldn't be an issue.

For that DACT, how much? PM price, I might snatch it up for my Beta22 build

i can tell you that it is an attenuator

when i was ordering my MK VI, Dave sent me an email saying something along the lines of "we just got the potentiometers in a few days ago"
