Buddy got a 299A (7189) model that has an open bias/phono tube winding... I'm looking for specs on the PTs used in 299A, and later models (with 7591s, I believe??)
TIA

Does he want to replace the whole transformer or will he be happy using an add-on for the open winding?

Hi,,,
I found a suitable 24V tx, and built him a doubler that will fit the foot print of the original damaged bridge,,, caps and diodes will be mounted on a tag strip on top of the tx, to save space,,,
That way he can continue rebuilding/testing the amp,,, and doubler ckt will be reversible if he gets the PT rewound or finds a replacement,,,

i have a working power traffo for the Scott 299, i built a separate 230vac replacement, too bad that i am in the other side of the pond from you...
Thanks for the reply,,, I'll pass this message to my buddy,, I'm sure shipping would be the killer tho!!!
i have a dynacost70 power traffo, a scott 290, a stromberg carlson pp 7408 amp all still at 110 volts ac primaries...
