Increasing cap size for c18 & c20
Have an order going to AES today but before processing I was wondering if I should get two 100x100 multi's for c18 & c20 instead of one 50x50 and one 100x100?
Hangman laid out a very nice way to do the job here...
http://www.ampegv4.com/forum/viewtopic. … 614#p12614
doing so gives 50uf for both the screens and the plates.
going with 100x100 for both c18 & c20 will allow the level capacitance for the plates to be bumped up to 67uf.
I'm not concerned w/ reinventing the wheel or changing the tone here just thought upping to 67uf may add more filtration
Or just stick with the 50uf????

Re: Increasing cap size for c18 & c20
the Dual 50uf is fine, and almost half the price. if you get the dual 100 you would only use half of it.
I have tried to look at your picture but it doesn't show up in your post for me, and when I follow your link: http://www.vulcanforums.com/forums/pict … reid=10769
I cant see anything either. the page opens and it is just a blank white background.

ok I will build w/ 50uf on the plate and screen and skip the 67uf idea for the plates.
the vulcanforum link gets cut due to the file size so I moved to photobucket
If you can see this... did I get it correct??

I can see it now. yes it looks correct. I have done the bleeder resistors on the screen supply and also left them out. I think putting them in is better form.
that is pretty much the way I do V4s/v2s and it seems to do very well.

Re: Increasing cap size for c18 & c20
Excellent! Thanks for dbl checking my work.
I can't wait for my parts to arrive to get this behemoth back to its former glory. I already rewired the speakers... got rid of the crap lamp cord and put in 14ga mil spec (teflon/silver) wire.
Cosmetically, its quite clean. Even came w/ the OEM dolly. Interesting combo of speakers.
