Got a pair of Dyna MK III's in for repair. Customer is interested in
upgrading. I have done a little research and found an Alan Kimmel driver
board at Welborne Labs and a cascode 12AU7 & 12BH7 driver board at
Triode
Electronics. Both also have PS board upgrades. Kimmels being a mosfet
pass
regulated design, Triodes's being a simpler a cap upgrade scheme.
Any experience/opinions on sound & performance on these
or other recommendations?
Thanks & happy new Year to everyone.
