So with the lead rings and the 6A3s the microphonics went waay down. Then I went and got much more efficient Tannoys so they became more of an issue again. I'm looking to a attenuate the output of the pre. Can I not put in a pair of resistors inline between the pre and the amp? If so what values? The loudest I ever listen right now is with the coarse on the third click and the fine all the way up. So basically just over half.
Thanks in advance.

The best place (IMHO) for the attenuation is in the power amp at its input. Can you, or would you be willing to, modify the power amp?

Sure, I don't mind.

So what size resistor should I use?

Analogluvr said:Tried the lead rings and there is a huge improvement!! I had the Teflon rings and they did virtually nothing. Just a suggestion but maybe the powers that be at bottlehead could source a sack of these and sell them as an optio. With the Beepre. With a few dollar premium of courseI would consider these a necessity.
Has anybody used them on their power amps? I'm wondering if the greater heat might melt the vinyl? I wonder how they would fare on the 845s as well? They kick out some serious heat!
Your feedback is appreciated!
I used them on my Stereomour (2A3's) and did notice some stickiness/melting. They did not stick to the tubes. I put some aluminum foil on the inside of the ring and it works just fine.
Those Teflon things....bah! throw them out... I don't think compression does anything noticeable. Mass! Mass! Mass!
