Hello all,

I need to replace some caps on a vintage Neumann U67... 500uF/40V and 25uF/385V
This values are hard to find... if I go with 470uF and 22uF should I get any problem? the fisical space is too tight to fit paralel caps, and as long as they are in the PSU part, I think I'll ge no problem with ripple using this values, am I right?

I need a service manual for the Summit TLA50 tube leveler... I replaced the 12AX7 inside, but need to adjust some trimmers... the sound is way low that with the other used tube. Can anyone help me with this?
Cheers,

E K
 
The Neumann will be fine with the close values. Also modern caps are much smaller than the old ones, you can go up a step if you want, but 470 uF is fine for the LV ones.
