@Zen, Pot problem with "Crrrr" during rotation has gone after setting Bias to ZERO.

Hi Guys,

Now that my plitron "Over Kill trafo" has pretty much turned into "kill trafo", I need to find other sources for a transformer.

Has anybody successfully used the Apex Jr Mercury Magnetics TA110-W? Which other trafos have you guys been using?

Thanks,
Dinesh

why not - if you use two of them , to have twice 40Vac

you can always ask AR2 which one from Apex he use

I am going to use the MM TA110-Ws for my Pumpkin-Shunty AC power supply. Doing a quick hookup to check voltage, two MM TA110-Ws can be hooked up to supply a nominal 40V - 0 - 40V or 48V - 0 - 48V, the latter too much probably for all but the lowest of line voltages -- Japan perhaps @ 100VAC line.

The transformers appear to be good quality E-I core and should have no problem supplying the required current to a stereo pair of preamp-regulators. In typical DIY overkill fashion, I picked up 4 of the TA110-Ws so I can go dual-mono.

The price is certainly very right!

Steve,
Thanks. The price surely is right. I was planning on ignoring the 48V taps and use the 40V. Have you tried putting any load on them? Connect a 100W lamp maybe and see how they might perform. I might consider using 4 as well if I have enough space in the cabinet.

Regards,
Dinesh

Hi Dinesh,

I have not checked out the load regulation of the trafos yet, but maybe tomorrow night a work I might have time to do so. Looking at the physical size and with my plan to use two per channel, I figured they would be well within their current capabilities and voltage droop loaded would not be a problem.

I plan on having the transformers and rectifiers in a separate box and bring only DC up to the preamp enclosure.

Please do.

Wow, 2 Box design huh? Worried about interference or simply no space in the cabinet? The rectifiers are on the Shunty board, just curios, what would you gain, by building a rectifier in the other box?
