Title: Need a Magnatone Model Custom 250 tube layout
Post by: mrr3000gt on May 22, 2025, 10:16:23 am

I have a blank chassis w/o tubes in my shop: a 1960-ih Magnatone Model Custom 250.


The issue is not fixing it: the chassis is UNMARKED and there is nothin on this amp I can find.


Does someone know what tubes should go in it? It does use a pair of 6973s, 12DW7.


No schematic on this and not sure what it is related to to have an idea what should be in it.

This is my best guess on the tube compliment. I will confirm if this is it when I find out 100% sure, but I am 95% sure now.

Your sketch says "Magnatron"  not "Magnatone"
