    Cap swapping...

    Post by Pooch on Wed Feb 27, 2013 3:52 pm

    I've put a Mundorf SIO .22 cap in C1 (normally a .1), on my VTA MK4s. Should this pose any problems long term? I like the sound, with AudioCap Theta .22 coupling at C5 and C7. Also a .1 Theta at C3.

    Hi Gordy,

    You can normally go up one size in caps like that with no ill effect. The .22 uF in place of the .10 uF should cause no issues with the amp. I think that C1 looks at about 125 to 150 volts. As long as that cap is 400 volt rated or higher you should be OK. Maybe be even a 200 rated cap would work also but I would feel better if C1 is 400 volts.

    Thanks, Bob.As much as I like them at C1, I pulled them and put them at C5,C7.I put the .1 Theta back at C1. I think I'm going to order a couple of .1 Mundorf SIO or gold silver in oil and stick those at C1.
