Re: Another One
I just finished up a home brew 6G3 and it has the same issue with the volume controls. It's an angry little bastard!
At 1 it's not loud enough.
At 2 it's plenty loud.
At 3 the cops are on the way.
I'll have to try the CTS 1M Audio's.

Re: Another One
Maybe I am misunderstanding something but, tell me if I am on the right track.
A 10% taper pot will achieve 10% of the total resistance value at half rotation.
A 30% taper pot will achieve 30% of the total value at half rotation.
Wouldn't a 30% pot be more touchy at lower volumes?

Re: Another One
Yes it would.
The CTS is 10%.
The Alpha is 15%.
The Alpha is touchier.

Re: Another One
Not sure where I got the 30% number from....
I have a PEC and CTS that may work better.
I'm really liking the sound so far.

Re: Another One
Damn, now I'm needing 10% CTS - it took forever getting the 30% ones that work so good on the ODS Dumbles They work fine though for now - a bit more range going from zero to hero might be useful. I keep a look out for a pair. Found some I think, will have to wait till Monday now

Re: Another One
Tom,
Antique electronic supply has them https://www.tubesandmore.com/products/p ... rand%3DCTS
so does Watts.
AES has better price.
Not sure about the taper though.
maybe someone can chime in on that.

Re: Another One
You'd want this one: https://www.tubesandmore.com/products/R-VC-MA. Pretty sure it's 10% taper. The difference between this and the Alphas is that it's a true log curve. Alphas aren't, which is why they come on so fast.

Re: Another One
I agree with this. I do a lot of home, late night playing, so I throw in 10% tapers in for all of my master volume pots (I generally save the 30% tapers for the tonestack).jelle wrote:+1. This is where the standard 10% CTS audio pot really works well.aflynt wrote:Yeah. Try a CTS or PEC audio. The Alpha audios come on fast.

Re: Another One
Have any of you guys tried a cold bias on the 6V6's to reduce head room?
Right now the power tubes are at 12w per tube at idle.
With B+1 @ 377vdc
I haven't tried it yet because it will require different power resistors.
Or a lower gain tube in V1 or V2?
I have to turn it up quite loud before it breaks up and that is with a humbucker guitar.
Should I sin and put a master volume in it?

Re: Another One
So I played around with a JJ 12AT7 tube today.
First I subbed it for V1 with a 12AX7 in V2.
Earlier break up with some clean tones down lower but it is a dirty clean.
You can modify it some with your guitar vol.
Turned up it sounded pretty good.
I only have one 12AT7 so then I tried it in V2,
Much earlier breakup, not as loud.
Wouldn't be bad in the right circumstance where you need more distortion than volume.
I think I like it better in V1.
I may have a 12AY7 around here some place to try that.

Re: Another One
Tom, if you want breakup at a lower volume, build an Airbrake like attenuator.
