I found this to be very helpful. Thank you, Don

I rank Telefunken or Mullard 12AX7's and 12AT7's as the best overall, but they are costly. However, should not be a major consideration for a Mac owner :>)

After buying all of these tubes & trying them in my C-2200
Here are my results.

Telefunken 12AX7 & 12AT7
Phillips JAN 12AX7 & 12AT7WC
RCA NOS 12AX7 & 12AT7

Not tested but received good comments about
Amperex
Sylvenia Chrome Domes

In my MA2275's preamp section I replaced the 12AT7 Drivers with NOS Mullard CV4024's, Re-issue Mullard 12AX7's for the tone control preamp tubes(the tone controls are defeated and thus out of the circuit most of the time) and Sovetek 12AX7LPS in the Phono Preamp section. Great tone and low noise also you are are spending about 1/5 of the cost of Telefunkens and Amperex and most likely have a quieter Phono section.
