Fantastic!

Yep...that is probably one of our original transformers in the Gretsch 6160. Is it this one? (see link below):

Valco Supro Thunderbolt Style 35W Power Transformer, 117V, E-3738, 330-3738, E-3738A, E-3738B

We recently reintroduced this part as well as a few others as part of our ClassicTone line nearly 50 years after they were originally produced by us.

Thank you sir! Enjoy!

Yes, we now offer upgrade versions of both the power transformer and output transformer for the TSL 60. I have supplied links to our webpages with all pertinent information as follows:

50W / 60W Marshall Style JCM2000 Power Transformer Upgrade, 120/240V, 96B-17

50W / 60W Marshall JCM900 & JCM2000 Style Upgrade / General Replacement Output Transformer, 4/8/16 Ohms, 784-348

Also, following is a nice optional upgrade choke:

Marshall 3 Hy Plexi Style Choke

The original amps did not come with a choke and the addition of the choke will help reduce the hum of the B+, improve filtering of power line generation noise and provide purer DC on the screen grids of the power tubes and the plates of the preamp tubes.

Thanks for your interest in our ClassicTone transformers!

wow~! i like it.

Just want to throw out another recommendation for the Classic Tone products.

I used their 18026 OT and 18046 PT and a 3H choke in my '68 12000 plexi clone and they sound amazing. The PT runs super cool...I can play with that thing cranked for hours and still put my hand right on the PT...and it barely feels warm. Excellent quality and service from Joe and Magnetic Components.

And all their spec sheets and wiring diagrams are available in PDF from on their website. This way you can sort out any wiring installation questions ahead of time to make sure you install the right part and it's done correctly.

ClassicTone

Thank you sir! Your kind words are appreciated!

Hey Guys, Checked out your stuff and am really excited that I can finally build my JCM 800 2204 50 watt head and will be using your PT, OT and Choke.....However, I need the part numbers and also if these could be shipped to India by your dealers/distributors? Any information is highly appreciated.

ClassicTone

Hello Aryasridhar,

The appropriate part numbers for the JCM800 50W amps are as follows:

40-18023 (PT)
40-18025 (OT)
40-18032 (Choke)

I believe both of our distributors, Amp Parts Direct and Triode USA should be able to ship to you in India. Following are links to their order pages for these three transformers:

Fantastic!!!!!!!!!! Thank You so much for the quick response!!!!!

VanR

Got my Classic Tone 18 watt OT from Triode on Wed. Sounds great in my 15 watt Plexi with JJ 6V6's. Think I'm going to pick up another one soon for the backup amp.

ClassicTone

Thank you sir!

I am glad you like the 18W Marshall OT (our ClassicTone # 40-18037).

I want to mod the mg2fx to take the hiss out of the hi-gain 4-9 mod of the amp. For my haze I replaced the R-57 with the upgrade choke so that took that out of my Haze. Thanks again.

Micky

Which Haze?
Do you have more details about the choke mod?

Hey everyone, brand new member and own a black 2555. Bought it brand new and still use it.

Ricochet

I would like to know as well. Particularly interested in a beefed up replacement of that puny OT that is in there now.

We do not offer anything currently for the JCM2000 DSL401 (40W?).

As of now, we only offer transformers for the 50W and 100W DSL/TSL amps and do not have any specific future plans for the DSL401 transformers.

Thanks,

ClassicTone By Magnetic Components, Inc.

VanR

Got my second Classic Tone18 Watt OT from Triode. Sounds as good as the first one. Thanks for the great sounding transformers at great prices. Glad I could buy Made In USA for a change.

RickyLee

I was posting about this in the Workbench section, but just remembered we have a dedicated thread for ClassicTone.



Hello Joe!



I just (finally after about 7 months or so) put my ClassicTone 40-18084 power transformer into my TSL100 this evening. Only played it for a few minutes at low volume.

I am a bit bummed though. I am only seeing about 10V of a reduction on the B+ or plate voltage of my EL34's. The specs claim that there should be a 10% reduction.

Anyone else here tried this power transformer yet? And if so, did you see the 10% reduction on the B+?

ClassicTone

Hello Rick,

Sorry to hear that it did not meet your expectations but I just had both my engineers verify that our 40-18084 was actually lower than your requested lower rating you actually supplied us to meet of between 450 - 460 B+ plate voltage. Our actual bench tested loaded winding reading was 443V.

Please keep in mind that you might want to give it more time under load at a bit more volume than you did to get a more accurate reading.

RickyLee

Hey Joe.

Yeah, I am thinking that this one I have might be a bit higher due to it being one of the first they made. I have been running it every day for a few hours and it is running loaded with four EL34's at around 472V on the EL34 plates. My MAINS are at about 122VAC with this plate voltage.

Once these power transformers are built, there is no way to modify the windings? 450V is a good voltage for all these new production power valves. The JJ's seem to hold up well running over 470V plate and screen.

Can I get a favor Joe? Can you ask the engineers a question for me? They put an additional winding on this power transformer for me. It is a 60V winding to take the place of the original 43V bias winding. Only problem is they did not put a center tap wire on this new 60V winding, where the original 43V has a CT and is used by the DSL/TSL.

Can you ask them if I should Ground one end of this 60V winding then just use the positive end in a one diode/one leg setup for the bias circuit?

ClassicTone

Yes. You can ground one end of the bias winding.

From what my engineer told me, this is typically they way Marshall did it.

NewReligion

I just installed a 40-18023 PT in a 50 watt Plexi. Sounds awesome!!!!

Thanks Classic Tone.
