- 2 stage 6C45PI valve with passive RIAA
- Silver mica Riaa caps, Mundorf coupling caps

Power amp:

Scheu based turntable with Kuzma arm and Shelter 7000 cartridge.
TVC is a wiring nightmare, but worth the effort
Music
About 1300 lps. Approximately 1000 Rock – modern stuff, 150 classical, 120 Jazz and Blues and 60 or so World music. Although that doesn’t really adequately describe the genres… I have to catogorize them somehow otherwise it’s hard to find them!
