Ampro amplifier fuse keeps blowing

[Patrick Ryan]

Hi folks,
Just acquired an Ampro, hoping to get a decent amplifier together, but found that although the projector runs fine, the amplifier fuse keeps tripping and blowing. I have checked, physically the fuse connection, but it looks okay. Any ideas please. Thanks

Could be a defective valve. Take them all out and switch on the amp, if OK, replace each valve in turn and each time do the same as the first one.
If it isn't one of the valves, no doubt it's a faulty electrolytic capacitor.
