Need a tip to convert Marshall Lead 12 from 240v to 120v

Post by chopstuck »

Is there a way to rewire the PT for operation on 120v ?
Currently using a low dollar plug in voltage transformer that works OK but may be a bit under spec-ed for OD duty.

I have checked out the schematics and a different PT was indicated for each of the two voltages.

The PS has a full wave bridge recto already so plan number one is out the window.
Any other thoughts as this amp is in really good nik. I would hate to let it go cheap. They sound so damn good.

I will throw in a couple of pics since there seem to be extra taps on the PT.
Heavens, an unused PI input !

Looks like the PT has a dual primary, which you can reconfigure for 120VAC.

Thanks Martin !
I got it rewired and tested. Works fine on 120v now.
I then put in a proper US voltages power cord and an 8 ohm speaker out.

All smiles and thanks a bunch !

I was not sure since I saw two different schematics for this amp with two different power transformers.

Drop by for a beer sometime. I'm just north of the Willamette on I-5.

I owe you.
