Re: JTM45/100 Dual OT schematic
I have some somewhere (cannot vouch for correct schems as I have not sat down and wired the amp up yet) I need to scan and post them here somehow.

haha, so the alleged 100w amps ran a 8k primary. ouchmaxbauer wrote:Roe wrote:Tommy wrote this on PP:

Hi guys, im new here!
I had to dig up this old thread, there is so little information on the Dual OT amps.
From what i understandt about transformers is, if you wire them parallel in primaries, and secondaries,
the impedances stay the exact same. because the transfer ratio stays the same, only the power
is divided on two irons causing less heat on either. The tubes are seeing the same impedance
as they do with one trasnformer. - given that they are the same irons.
Anybode want to chime in again on this subject?
I could not get any schematics of the old 45/100s, they are not available anymore
if someone could repost them that would be great.

hi Neill, that would be great if you could post a schematic, i cant find it online anymore.
cheers

it would make more sense to wire the secondaries only in parallel in this case, i am not
sure anymore to be honest haha.
looking forward to see an original plan
