After reading back a couple hundred pages, I have decided to investigate which capacitors came inside my T1. (There were quite a few posts about people opening their units up and finding a variety of different caps, some good and a lot that weren't so good).
I opened it up this morning and this is what I found:
Headphone amp board coupling caps = ELNA (M) (brown) 47uF 50V (I have no idea what kind of ELNA caps these are...)
Headphone amp board rail voltage caps = Nichicon VR (M) 470uF 25V
Secondary power supply caps = Purple (Panasonic?) 962TN 330uF 35V
Main power supply caps = Nichicon HE (M) 3300uF 25V
Pretty sure these are different cap combinations than the ones posted by users previously in the thread, so I guess maybe every T1 is unique :P
After reading CoiL's posts, I plan on upgrading these to ELNA Silmic II's, and also upgrading the main PS caps to Panasonic FR's. I ordered them up today from a vendor (with a spare of each as well) for around $20, so not too much cost. I plan on doing the soldering in the next couple weeks, so I'll post results later if anyone is interested.
Seems to me to be a cheap way to perhaps get better sound out of this already great unit.
