Tfm 45 lost power!

Post by 70chevelle » Sat Sep 24, 2011 7:24 am

Had my system (tfm45 and ct6) playing last nite and had to run to the store and left it playing. Came home and all was quiet. No power to the amp? I pulled the fuse and checked it with my meter and it's showing resistance. I plugged it in to another outlet and nothing. No initial buzz, no lights, etc. Weather was fine, no storms and all the other equip is fine. Any thoughts ?

check breakers of the room or try each unit in a known working socket.

I'd pop the top & see if there are any obvious signs of failure. Check for leaking/exploded caps, burned spot, etc. If you aren't even getting a click or anything, I'd guess there's a power issue so I'd look there first. DO NOT touch any parts inside either as caps will store qiute a hit for long periods after being unplugged.

Thanks. I did the known socket routine. Opened up the case and didn't see any obvious clues, nor was there any unusual smells. Not a good day.

If the fuse is showing resistance it is bad. A good fuse should show 0 resistance.

I'm just sayin'.

Frankie is right. Fuse should read short or 0 ohms.

In theory, yes. In reality, not exactly. Some of the fuses measured at CF showed a miniscule bit of resistance. What was the exact measurement in ohms?

Not sure of the exact reading, it was bouncing around quite a bit, but off to Rat Shack for a new fuse. Fingers crossed

Huh?

Bouncing around? Now that's abnormal. You sure the batteries were good in the DVM?

if the fuse doesn't cover it, you have tom at vintage hifi, rolland at hi-tech, and bill at bob carver's repair center.

We can fix it. However, sending it to the closest shop is prob. the best option. Shipping can be a bitch.

Beemers, I can drive it to you. I'm about 45 min east of the city. Rat shack didn't have the 12 amp fuse but they checked mine and it is blown. That's the good news right now. I'll have to order fuses on the net and wait for them to get here and figure out if it is something more. If so, I guess she'll get delivered for repairs.

You can throw in a 10A for testing. If it blows, you have a direct short.

Does it have to be a ceramic fuse? I ordered the 12's but wont be here until next week. I have 10 amp auto fuses to test with if they will work?
