Tone Stack Treble Cap

[RedPlated]

Yup, that's what I'm leaning toward too. Just trying to source a 250K linear push/pull, which is proving harder than I thought.

The Laney GH/VC etc series have a 220n bass cap. Just makes it sound even more boxy to me

Laney protube series have a switchable 22n treble cap on the 'midboost' switch, which probably just has the effect pf bypassing the tone stack

I think you're talking about different caps? This thread is about the smaller tone stack treble peaker that's around 470pF - 560pF in most amps. You seem to be talking about the larger 0.022uF caps?

Yeah that's my backup choice haha. I wish Alpha made one that's closer to CTS' version with SPST switch:

I have a little Single EL84 amp I designed.. I say that losely as it's an ongoing thing.. I try this I try that.. I like it and then I don't..
It took me a while to realize a Cathode Biased Amp with no negative feedback is bright as fuck if you just use common specs..
I just switched the 470p Treble Tonestack Cap to a 250 and it went a long way to tame the highs along with a few Plate Snubber Caps..

Yah i was getting off topic and talking about the other tone stack caps.
If you play with the TSC, you'll notice that making the treble cap larger just lowers the high pass frequency cut off point of the treble control, which eats into (raises and shrinks) the mid-dip, and eventually just forms a complete bypass of the tone stack
