would it be possible to put the new iron upgrade in the original sex amps. I know I would probably have to change the power tranny also. But would it be possible to put the new sex design in these and get monos,with new iron?Jan Olsen

No. The plate choke cannot handle the necessary 60mA, and the 4K transformer impedance is a little high - 3K is better. I am hoping to have a better plate choke eventually, but meanwhile you could use the Hammond 158L choke with a Bottlehead OT-1 or Magnequest TFA 2004Jr.

I have a draft article on the Original SEX and its options, not yet edited. I'm out of town right now, but if you want a draft, send a PM with your email address and I'll send a copy next week.
