I have tried some other caps that I didn't quite care for but now would like to try the Solens. So far the biggest improvement was connecting the ground lugs together. Now I think it would be a good experiment to try the Solens. I need some for another project as well.
It seems that many of the original Altec caps have degraded. Has anybody actually measured a bad original Altec cap?
Rontec,
You need 6, 8, 16 & 21 capacitors......1 of each total value.
I used 2 x 3 for the 6's, 4.7 & 3.3 for the 8's, 16 for the 16's & a 10 & an 11 for the 21.
These were all available from PE. I used 400V Solens.
This will make the biggest difference you can make to your 19's....way above all the other usual mods.
Now to get the new resistors...& I wish I had done this before as they are now buried underneath the new caps. Ah well....the things we do for old Altecs!!!

Thanks everyone for the info. I'll post later what I find out with the Solens.

Exactly....Maybe I should order resistors now too!

Just one more question then, how are they wired into the circuit when you use two to create a specific value?

Not sure whether you call this series or parallel, but you just solder one to the original connections & then just solder the other one to the same connections. That is, solder both the 2 smaller values to the same original connections to get the original larger value.....hope that's clear.

Yep that's clear, I sorta figured that would be the way.
I'd call that parallel....
Thanks!
