Made quick clips last night now that I can use my Attenuator with the new Marstran transformer installed. I realized I need to stop putting reverb on my mixdowns since there's no need for it on tone comparisons:

You changed the PT on that one too, IIRC ?

Yup... I used a generic power tranny, not a Marstran. But I'm contemplating putting it back to the original PT to crank up the voltages from the steady 470 to its previous 535.

How about the choke ?

OEM or aftermarket ?

Same cheapy as the PT when I got them at "tubesandmore.com".

I might upgrade the choke someday, but I can't really prove how much a quality choke can help the tone.
