1987 PT OT Choke for 6v6

[23h2o]

Hello , Im having a really hard time finding an answer to this and thought this forum may be the place for help.
I plan to build a marshall 1987 circuit with a 6v6 power section, ss rectification. I need to know what pt, ot, and choke would work for this application.... Preferably hammond or heyboer.

Im new to amp building, but have modded a few and built numerous pedals from scratch. Will be using a ceriatone kit but want to save some cash on shipping etc by sourcing my own transformers and choke.

Any help is appreciated, thanks sands

so ive been recommended the PT jtm 45 @ 460 B+ from MM and the FO50BM-X output (59 tweed bassman 8 k primary 4-8-16 taps)

Sound right or no and being that these are MM what would be the hammond or heyboer equivalent?

thanks

Whoa! For a *real* 6v6 that's an uber-high plate voltage. I've been wanting to try this as well, but have not yet looked into the X-Formers.

Yeah thats what I thought as well. I wish someone would just say use this and this and your good, but i have of yet found an answer.

Some quick sleuthing, I don't see why this wouldn't be a fine choice with B+ options, and if you check the specs', it gives the (approx) B+ voltage with the different taps and rectifier arrangements.

Didn't check the hole pattern, but making an adapter plate isn't that big a deal. There's also a stand-up version of this.

Got some info from a known marshall clone amp maker.....

Heyboer 784-139 OT....1202-118 PT...... Classic tone carries these JTM50 replacements. Still have to mismatch the cab/amp ohm for 6v6...

How would the 1987 circuit sound married to the 18 watt el84 power section?

That PT is still going to give you a high voltage, and why not use an 8K OT so no need to mismatch.
Magnetic Components JTM-45 has just that. Kinda overkill for a 20 watt amp, but what do I know? I haven't tried it.
They also sell the Fender OT's used in their 6v6 amps. Much smaller, compared to the Marshall OT.
