. . . C807/C808 are in the feedback loop and an audio grade bi-polar is recommended, I will let Ben chime in on this if he is following.
What is the advantage over a polarized audio grade electrolytic?
Great job again Pat
Only question I have: would using a Wima film cap instead of a COG also make an improvement or does it have to be ceramic?
These are great little amps once restored. Tons of bottom end. LOVE the Silmics - they revolutionise the sound.
Yes you could use a Wima FKP they are available from Mouser in both values needed. The problem is with the fit. The phono board would be a tight squeeze, looks like the amp board would be fine. You also have the option of mounting on the back of the board if you choose.
Yes I am lovin' the Sansui sound! I just got a 505 here and am going to see what she can do with some all out upgrades. Will post a thread when I get started.
Thanks Pat
Did you keep the 2SC871's in there or replaced them as well?
...and don't forget the 777 series. I have the "a" version along with two 555a and a 505. The 505 has impressive low end and can project a sound much bigger than its 23 watts calls for, whereas the 555a has better definition higher up the register. I might even pick the 505 if I really had to choose between the two.
But the 777a is a true class act and the king of the cap couplers if you ask me. I'd even pick it over a 999 a 517 and an Eight, but not an Eight deluxe.
Great job again Pat

I have a 505 here now and I think I will try the C0G and Wima FKP on the amp board, and see if I have a preference.

I am the very fortunate new owner of this beauty. Thank you, thank you, Pat! You are a genius!
When I hooked it up today, I was stunned. To give you an idea of how good this unit sounds, it rivals my McIntosh MX110/MC2505 set up using the same sources. The sound is crystal clear, detailed, distortion free and very warm. Very much like a tube set up. The mids are wonderfully executed and the bass is tight, focused and vibrant. You can feel the vibrations on a string bass! The highs are lush, expansive and sweet. Pat was right. This unit is a sleeper. Count me a believer. This is my first Sansui. It may not be my last. I may sell my Mac gear!
In case you want to know, the speakers are Reference 3A mm de capos, the TT is a Thorens TD125MKII, the tuner is a Jolida 402 and the tape deck is a Pioneer RT707. I am in heaven!
