I just had some mods done to my 300B amplifier.
One of the mods was to replace the stock power iron with a "beefier" piece .....
I have the original which still works just fine and thought some of the DIY folks might have a use for it.
I checked the price of a new one and they go for $85.00 and up from different suppliers.
If you could use this transformer in a project, make me an offer .....
Thanks,
Randy
