WJA Electron pre-amp (me)

- 2 stage 6C45PI valve with passive RIAA
- Silver mica Riaa caps, Mundorf coupling caps
- Kiwame resistiors excpet RIAA which are 0.5% metal films
- Transformer Volume Control, 23 steps, which makes a nice balanced line stage too if you don’t need a lot of gain there.
- Shunt regulation followed by CCS valve anode loads (overkill perhaps, but it’s damn quiet)
Power amp:
- WJA Electron 6C45PI / 2A3-40 SET amp (about 6-7 watts a channel)

- I made a silent PC running on Ubuntu and bought 1 of those cheap 196Khz 24bit DAcs to play with.. Promising.. work in progres
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!
