Thanks for the replies .
I have purchased a nice restored set of MC30s from Yves Beauvais at Vintage Vacuum Audio.I should get them this week sometime
They have been completely redone with all new resistors capacitors and wiring .
If in the end i do not like them , i will try the Air Tight ATM-2. I currently use a Rogue Audio ST-100 With NOS Mullard 12AX7s from the 1960s .
