Hey everyone,
I'm looking to build a pro bias board for my Stax SRD-7. I found a guide at Headphonia, but want to make sure my selection is correct before finalizing the order. They don't list the type of caps used, only the specs needed but there's a picture.
Guide:
http://www.headfonia.com/stax-srm-1mk2-bias-modification/
Pic of their board:
Parts:
VR1: 500k Ohm, Single Turn
R1: 470k Ohm, 1/2 Watt
R2: 33k Ohm, 1/2 Watt
R3: 2.7M Ohm, 1/2 Wtt
R4: 2M Ohm, 1/2 Watt
D1, D2: 1N4007 (or other diodes with ratings above 800V)
C1: 0.1uF 630V, AC Rating
C2: 0.1uF 1000V, DC Rating
The parts I'm questioning:
R3 and R4, am I right assuming these are carbons (the white ones)?
C1 and C2: are pulse film capacitors acceptable for the usage? (schematic at the above link, but they're the only two caps shown)
