Sources: Rega P2 w/DL-103, NAD C521BEE w/OPA627 op-amps & output cap bypass
Preamps: Rotel Phono w/LM4562 op-amps & output cap bypass, Bottlehead FPIII w/upgraded caps & RCA Clear-tops
Amp: Dynaco ST-70 w/original iron, tubes4hifi driver, RCA clear-tops and JJ KT77's
Speakers: Klipsch RF-7's
The ST-70 driver is the original tubes4hifi PCB. I am in the process of removing it and replacing it with the new Lo Gain version due to the 102db efficiency of my new RF-7's. I also want to use Auricaps this time. Last upgrade for this system will be a Bottlehead Seduction tube phono preamp.
