Amp (Transformer)

If it was shorted the fuse would have blown, if the fuse is bypassed it would have smoked.
You need to to check for AC voltage at the secondary if your meter is not already damaged. Are you sure you are safe to be doing this?

 

This. Amp has enough voltage to be deadly, unless you know exactly what you are doing, never play inside an amp.

 

There's a big difference between getting bitten by 120v AC and getting hit by the 400v to 700v DC that is common in tube amps.

Take it to tech.

By the way, the secondary of transformer is basically a wire coil. Now you tell me what the reading of your ohm meter should read. You can't check if transformer is ok that way. Well, unless it's infinity, then it's broke.

 

Buzzing in a test meter is a bad thing, it usually means you have exceeded design values for arc-over. You meter needs to be rated for at least 1 KV AC.
Why are you starting at the transformer first if the fuse is not blowing?

 

The resistance of a power transformer is pretty low. The number of wire turns and gauge of wire is radically different from pickups.

 

Oops. I saw "biggish amp" and "transformer" and automatically read "tube". Sorry 'bout that.

 

What? Shorts in a transformer usually will burn through the separating insulator and cause over-current.

 

The only way to test the performance of an output transformer that isn't obviously open circuit and therefore obviously dead is to use a heater transformer powered by a Variac to supply a very small voltage to the secondary and measure the primary voltage at the tube sockets.
Take this amp to a good tech as its probably a case of a little knowledge being a very dangerous thing.
You got a shock from the AC you won't be doing anything but smoking ever so slightly if you get across the DC ht if its got any working diodes in it.
Sorry just read its a transistor amp of some as yet un ascertained description best put it in the garbage then, as they are not worth messing with, when you can buy one that works and weighs nothing for about 30pence and a half chewed mars bar these days.

 

We are apparently talking about a SS amp.
IF the secondary had inter-wind shorts (isolated from chassis or primary) the secondary voltage would be lower, resistance still means very little unless it is a complete open. You need to measure AC voltage at the secondary and compare to the spec on the schematic.
DON'T GET SHOCKED AGAIN.

 

This whole thread has filled me with alarm. OP PLEASE take the amp to a tech. His bill will be much less than your life is worth!!!!

 

+1 I would buy a Aspen Pittmann Tube Amp Book or Gerald Weber's, Handbook.

And Keep your left hand in your pocket. When and trust me it's when, you do get that potential life ending jolt you don't want your heart in line.

I got hit with a TV high voltage and survived.

 

That's about par for the course around here, I have Aspergers and dyslexia, can't you just borrow a known good ecc83 for test purposes.
Is there any information on the amplifier, like make or type, or anything else us amplifier OCD junkies can get our teeth into.
