Lets forget about the size of the transformer, our interest in the power transformer is that it supplies our amp with the desired voltage and current.
The Classic Tone transformer supplies 650vac @ 200mA. The D'Lite transformer supplies 325 - 0 -325 @ 200mA. I'm sure that is the same as saying 650vac @ 200mA.
What I saying is the size of the power transformer isn't enough reason for me to replace the D'Lite one given the specs are nearly identical. What is there to consider beyond these specs?
Crazy Man, you are late to the party. Almost two weeks ago this was covered and he was directed to a close BN equivalent off the shelf PT(Vibrolux footprint PT, 2.5x3.125, 300mA from Mojo) that drops right into his chassis, with no additional work required.
FWIW, early the 200mA Brownnote PT that you posted was discontinued and wasn't applicable to some of the possible options the OP was looking for. If you read the entire thread closely you will see that Mark posted version 2, which is 300ma and I also remember Moss mentioning to me a 350mA version as well.
You just love being hostile TM. I think your attitude is totally uncalled for. Either get civil or lets start talking to the moderators. Which means no arguments, just a change of attitude.
In this thread a lot of transformers are being suggested which were all much as muchness.
This question isn't about what has already been said, reasons for their suggestions. In short I haven't seen a lot of science behind these suggestions. Which isn't to belittle anyone as this amp does come with a mind set where people don't question HAD's choices.
I was also curious why you feel you needed to replace the power transformer in your 4 X 6V6 build?
IMHO, the PT current rating is too small for a quad of 6V6's
(Page 2, your third post.)
In my mind HAD was using standard iron, and to deviate from this would be a change in tone. Given peoples tonal memory isn't as good as they'd like to think. I'm not sure most people wouldn't hear the change in response.
Late to the party - as usual. Got to get rid of the day job.
Great info guys.
I have the very same chassis and it's been yelling "me next"
I'm thinking 2 x 6L6.
I'd like to get a Lator/loop in there too.
Tight squeeze - hmm.
Thanks for all the info guys!

Mark for god's sake lighten up, this was just about a power transformer. There's no need to cry and then run to the virtual principal's office to snitch. Hostile never, I didn't think pointing out the highlights of previous postings was an argument. Nor does it require an exercise in psychacoustics or any deep reflection into HAD's part selection.
This was simple really, a bare BN chassis that needed PT iron to fit it's Vibrolux 2.5 x 3.125 mounting centers and cutout. I never stated I replaced D'lite transfomers with my own custom units did I? I did state that I sourced my own iron for the several builds I did do using the BN chassis. Why wait months to get units from BN (when you could get them)when I could just go straight to the source and have them in just over 2 weeks.
Yes, regarding that "quote" if you follow the proceeding posts it's in context to the OP pointing out that stock MCI Vibrolux PT to use for a quad of 6V6's. With a rule of thumb devoting 65-70mA per 6V6, 200mA would be undersized. The stock 200mA Vibrolux PT has a too small HT rating to the support four 6V6's let alone possibly four 6l6's that was thrown his way as well, this is where the custom PT comes in. Better yet, Mojo now carries now a unit that will drop right in that happens to be heavier in the HT, which will easily support a quad of 6V6's . Moss increased the HT rating to 300mA so it wouldn't run warm with the 44W units.

Bob, it's actually not so bad as the board is 1/2" longer and you can make it 3.125" wide as well. My Brownnote data mining folder was on my notebook that crashed. If I can retrieve that info, I should still have a BN board layout with the integral loop in that folder.
If you don't get it, then you don't get it. I'm not offended by being called crazy BTW. I see it this way, if you can't be civil then go somewhere where this sort of attitude is regarded as acceptable.
TM is one of the biggest contributors on this forum and has helped countless members with questions and problems, just as he is doing in this thread. I don't think these actions are warranted.
To take such offense to a post about a transformer seems odd. Maybe there was something that was misread or confused. I read this whole thread and nothing was inappropriate.

Somewhere I've got a layout for BN chassis with built in 'lator. Not fancy - pencil and paper.... Let me know if you're interested and I can dig it out and scan it. Also have lots of pics of the finished amp.
