Yes, it's my understanding that it was a schematic error, no JTM45s have been found that actually use the CLC supply for the whole amp.Tony Bones wrote: ↑Mon Apr 29, 2019 1:48 am I think it was only the very first schematics that showed the choke in that position. Were any amps actually made that way, or was it just a mistake in the drawing?
I think that a 5F6a Bassman, having a ~4k OT, should have more HT ripple than an equivalent amp with a 8k OT, as the latter should have a lower (loaded) HT current draw.
The earlier JTM45s used an RS Deluxe OT, wired for 6k6:16 ohms, whilst later ones moved to the 8k Drake 784-103.
