Replaced some parts in my M-60/3.3...

OTL Asylum

OTL, Output Transformerless Amplifier User Group.

...that I at-least-partially discussed with Ralph first. Replaced the coupling caps with 0.15uF Miflex KPCUs, copper-foil/paper and polyprop. with oil. They sure are big. :-)

Also added some powersupply bypasses, a 0.47uF SoniCap Platinum (Teflon and tinfoil) to the 200uF supply for the three Voltage-gain tubes...

...and one 1uF Platinum to each of the output-stage supplies.

I have one amp done* and will do the 2nd tomorrow.

AND...lucky me!...I didn't let the smoke out of the first amp!
.

* I've done these sorts of things dozens of times, but now I'm not merely older but also have sometimes-fairly-painful arthritis in my hands, and my back gets really sore from bending over amps for hours.
