I've been building some 2a3/6B4G amps and am looking to standardise on either the 2a3 or the 6B4G. I listen to a lot of classical music and want smooth sound with good tone and detail - no hardness (I find Sovtek unacceptably hard).
In 2a3:
Prefer old biplate Chinese to Sovtek monoplates
- Haven't compared with Chinese 2a3C
- Haven't compared with NOS biplate 2a3
In 6B4G:
Prefer old biplate Svetlana 6C4C to Sovtek monoplates
- Haven't compared with NOS biplate 6B4G
I haven't directly compared the Chinese 2a3 biplates with the 6C4C - different sockets and voltage.
NOS 2a3 seem more plentiful but more expensive than 6B4G. Chinese biplates are virtually extinct. 6C4C Svetlana seem fairly plentiful in Russia still.
Can anybody give me views on which way to go here - 2a3 or 6B4G? What would you do?
Andy
