Tonight my modded and upgraded R8 will have 90 hours of burn in. And it sounds wonderful. It took awhile to compleate the transformation. I’m 79 years young and have Parkinson’s. So I had to wait for non shaky days to solder. The only work I didn’t do was mess with the wiring. To much like spaghette. So I quite while I was ahead. I like Stephie worked a section at a time and then would test it for a day and then do another section. The bias board mod really brought out the heart of the R8.

My tubes are:

6N9S = 1579 = 6SL7 Matched/Selected Pair MELZ NEW NOS Metal Base

6sn7GTB Tung-Sol, NOS

Sylvania 6SN7GT 2-Hole BAD BOYS, NOS

Electro-Harmonis EL34
