PT 1204-43/subtitution?

[ac/dc]

Hi!
As this is my first post, hello to everybody!
Hopefully I'll bring some added value here...but more possibly I'll get:-)

I'm looking for Marstran transformer PT 1204-43 (dual sec.) for my JTM45/100 clone (Cariatone).
I'd like to have both option voltages - 490V for modern tubes and 560V for vintage GEC.
It looks like there is no stock at the moment. And another one I need also (1203-80)

I look at the Mercury M. - is there any chance to use their M-JTM-45/100P transformer as subtitution for 1204-43?
It's correct PT for JTM100...:
secondary, B+: 168-0-168 + 188-0-188 + 90V bias + 6,3V filament self leads.

Would pls someone comment how this would work?

Thanks and regards

those secondaries dont look right to me. should be more like 350ish volts

I know Roe.
What about any combination of secondary voltages?

I'd wait for Brian's transformer. Patients is a virtue.

+ 1. I have two of brian's 1202-43s and both are great

Yeah, I'd like to buy them both, but at the moment no stock, none of both.
If Brian read this I would appreciate any info regarding availability.

OK, I just took a peak and I have two new 1203-80's and one very old used 1204-43. I would have to check the primary on the 43 to see what taps it has before offering it for sale.

Excellent, pls let me know Brian.

Thanks!

Hey, new guy here as well! When available, I'll take a 1204-43/1202-84/3H package for my Ceriatone Super 100 kit too!!

Just keep an eye on the Marstran in stock page for inventory updates.

[FredD]

Yes, I check every day, twice today, thanks Brian! Gimme' that good word when you can!!

[Brian Wallace]
