I left this on for a total of about 40hrs over a week or so. The voltages stayed basically the same as before, no real shift.

I replace the 2x EF86 with NOS RFTs and the ECC88 with a NOS Sylvania. Here are the new readings with those tubes. These were taken after about 5hrs of leaving the EROS on:


A Side: (actual | target)
Kreg 1.1 | 1
breg 97.5 | 100
OA 159 | 170
IA 222 | 225
BA 0 | 0
OB 95.3 |100

B Side: (Actual | target)
Kreg  1.42 | 1
breg 98 | 100
OA 156.9 | 170
IA 223 | 225
BA 0 | 0
OB 95.8  | 100

These look a lot better, with the only outlier being the Kreg on the B Side, which i am not worried about.

Regarding sound. These tubes are fresh, but are noticeably quieter. With the stock tubes, the background noise floor seemed to worsen and became very obvious after a few days. It wan't bad, but quite noticeable on quiet sections of music - may because of very sensitive speakers?

Anyway, very happy with this and will update if/when.
