Hello everyone,
I am in the process of finding parts to build Tortello's headphone amp http://www.diyaudio.com/forums/showthread.php?s=&threadid=2451&pagenumber=1 and have a few questions I hope some one can help me with. (By the way i have never built an amp before so be gentile with me
).
1. The transformer. what VA and secondary voltage is recommended for this design?
I found an 80VA 2x25 toroidal at www.maplin.co.uk stock No.vs24b, would this be suitable?
2. I have not been able to find anywhere (maplins, farnell and RS) the zener diodes that are on the schematic which Tortello sent me, could some one recommend suitable a replacement?
3. even more basic question now, sorry.
On the schematic some of the caps have one straight side with a + next to it and the other plate is curved, while some (actually only 1, C2) have both plates straight. what is the difference?
I know that there are many different types of caps all made from different materials, what type would you recommend for sound quality (However i am on a budget, sadly
)
4. The Bias and Bal pots, are these trim pots?
OK I think that will do for now, I hope someone can help
Thankyou,
Kram
