Fuse Blowing on Superamp AE 25
Yes! The power supply is essentially a single transformer with a centre tap and two output windings. If that has gone it will be a bugger to replace. There are two chokes, so I will check their resistance now. 
Fuse Blowing on Superamp AE 25
Thanks for all the input. I have spent some more time reading and measuring. First, the Superamp does not have any bias adjustment - it is auto-biased - so I don't have to worry about that. Second, I checked the resistors in each bias circuit, and... 
Fuse Blowing on Superamp AE 25
I will still be waiting for fuses for a while, but I have checked all tubes with an ohm meter, and checked to fuses on the current source tubes. Nothing unusual. of course, it may be that the low voltage of the ohm meter may show nothing that occu... 
Fuse Blowing on Superamp AE 25
Thanks for the idea. I will pull out all tubes before I put in the new fuse, then insert one at a time. Would that cause a problem?No radioshack around here. No one I have shown the fuse to has ever seen one. Not an audiophile town. 
Parts source?
Thanks gentlemen. I will check those sources. 
Fuse : Voltage ratings
Howdy folks,Not exactly on topic, but close; has anyone had problems with the 2 amp AC fuse blowing on the 25? Mine went for no apparent reason and I cannot see anything inside the case that looks out of the ordinary. There is no sign on any compo...
