would someone explain why the Mini-Z uses a SS rectifier instead of a tube rectifier (i.e. 5Y3)? similar to the KT-45, can the Mini accept a tube rectifier if that is the user's preference? thanks.

The mini has a rectifier? ? I have no idea where it's hiding in mine. I believed it's just a 12ax7 and EL84 but I'm certainly no techie. I thought single ended amps didn't have rectifiers, but again I know next to nothing.

I thought single ended amps didn't have rectifiers, but again I know next to nothing. All tube amps have a rectifier of some description. The Fender Champs had 5Y3 tube rectifiers. I think you could convert it to a tube rectifier, but unless it currently has a plug in SS rectifier (i've never looked inside one, if it has this, just unplug the SS and put in a 5Y3), it would involve modifying the circuit, punching a hole in the chassis and installing an octal rectifier socket for the 5y3. Doable I think, but a pain for sure.

You would probably have to add an additional tranny to power the heaters .

i had no idea this question would be such a stumper. as for the modification i know it can be done, it is just a matter of how easy it is to make it happen. i guess my real is question is this and perhaps it can only be answered by the good Doctor himself. WHY A SS RECTIFIER IN THE MINI OVER A TUBE?

It is just the design of that particular amp. Why is it so important that you know?

Prolly just a cost effective kinda deal. Just wire a coupla diodes in after the power tranny and before the filters...Pulsating B+!

Even a page or two of stuff you have forgotten would give me a big boost.

I know, I know....WAY late.
The answer is probably this: Single-Ended amps don't sag like push-pull amplifiers when a tube rectifier is used. You're not going to get the same effect in a SE amp as in a Class AB Push-Pull.
Not to mention, who knows if the PT has a 5v heater tap for a tube rectifier.

Not only do you need a 5v supply for tube recto heaters, but you would need a center tapped high voltage output, which you don't need on a diode bridge rectified power supply.
