RE: Now that is a brilliant concept Brian!

Hi Bas
Yes I'm quite excited after our first listen - it definitely raises the bar with the biggest boldest and sweetest sound I can remember.
Yesterday I tried about 10 different sets of NOS/new 2a3 and 45 (globe and ST). I found only 1 pair that didn't have a problem with microphonics in this linestage: NOS 45st. These were also the smallest tube and had the least mechanical resonance when dinged with a fingernail. The next best were NOS 2A3st.
The worst were the globes, except the baddest of them all (rang like the Liberty Bell) - VA 2A3B single plate. That one has coil springs across the top holding the filaments.
We've got the hum tamed and now just trying to track down the source of some sizzle.
regards
Brian
