I've been asked to mod an AC-30C2. Finding the schematics was a pita, btw.
Does it use the same Sanecore OT as the CC version? I ask because the Sanecore CC2 footprint does not match original iron or the MM Woden the customer wants. You have to drill holes in steel (which I hate). It's all about scope....

Re: AC-30C2 -- question about the output transformer
Wish I could help you jaysg, but I have yet to encounter a C2. My guess is that it probably doesn't match the original Woden/Haddon/Albion/Parmeko etc... footprint. I do very much appreciate you sharing the schematics.
Thank you!
Interesting. No tube rect., no choke, DC heaters, non-traditional Bass(mid) control, op amps galore... Lots of "stuff" there...

Yes, thanks for posting the info!!
When I die, I want to go like my Grandfather did, peacefully in his sleep.
Not screaming like the passengers in his car!
Cutting out a man's tongue does not mean he’s a liar, but it does show that you fear the truth he might speak about you!

Re: AC-30C2 -- question about the output transformer
Yes, thanks for those schematics.
Interesting to use a 47uF reservoir on the plate B+ node, whereas 100uF on the screen grid B+ node.
What VB+ does it operate at?

Re: AC-30C2 -- question about the output transformer
Drilling holes in steel is easy. The mistakes that folks make are using a worn bit, and running the drill at too high a speed (which is likely how the bit became worn). At too high a speed it stops cutting and just rubs the bit to death. Start at 0 and gradually increase the speed - you'll see the amount of metal coming off increase, then level out, then decrease - back off some and you have it right.
