Which Classic Tone PT + OT + Choke ?

[PeterJ_22]

Hi guys, im building a JTM45 head with ceriatone chassis / plates, and components from valvestorm.
Which Classic Tone PT / OT / Choke would you recommend for this project? Im basing the build off the ceriatone layout / values and would like to hopefully have transformers match the chassis with minimal redrilling etc.

Any help would be greatly appreciated

cheers!

I guess you want 1202-55, 784-103 and 352-114?

Hi PeterJ_22,

Yes....Roe has mentioned the proper original Drake part numbers but the ClassicTone numbers for these items are 40-18033 for the PT, 40-18039 for the OT and the 40-18058 for the choke (or the 40-18059 20Hy version as an option).

Our distributor, Triode Electronics offers these as a transformer bundle per the following link:

Thanks for your interest in our ClassicTone Transformers!

is the 3H choke better suited to a ceriatone layout then the 20H ?

[PeterJ_22]

er Hy

[Roe]

both should work fine. its a matter of taste. 3h will sound rawer, 20h cleaner

[PeterJ_22]

Which one would be closest to the original JTM45 spec though? Is the difference hugely noticeable?
I play mainly led zep / cream / acdc / etc classic rock+blues so leaning towards the 3hy?

[Roe]

which specs? both were used

[libtech]

I was going to go for the 3h since only the early jtm45s seemed to have the 20h

[PeterJ_22]

Not to sure, Im basing it off the ceriatone layout etc no idea what one they use?

[libtech]

No idea which they use, the 3h would be more vintage correct though since the 20's would have been used with a rs style ot where as the mag com ot is based on the drake 103 ot which seems to be used ~65 on whith the 3h choke.
