Help with Crate V33 212 Amp

Hello everyone, I'm brand new here and have pretty much zero experience with the inside of guitar amps aside from swapping out tubes.

I recently purchased a used Crate V33 212. It was working fine until about one month ago when it just stopped playing mid-song at rehearsal.

I was playing at normal rehearsal volumes and all of a sudden just no more sound. It literally does nothing now. No LED light, no sound, nothing. So, I inspected the tubes and to my knowledge they are fine. I replaced the preamp tubes to see if that would help to no avail. I don't have any other power tubes to try but don't want to spend the money on them right now if that isn't the problem because they're non-refundable. I had all the fuses I could find (three) tested at my local Radio Shack and they were all fine as well.

It would be really great if there was an easy fix as I don't have much extra money to spend right now. I appreciate any ideas and thank you for taking the time to review my thread.

I've heard about the footswitch jack causing similar problems
try plugging a cable in and out of it a few times, see it it does any thing
best of luck

The switching power supply in those amps is very finicky and crate does not have replacements. I'm going to guess that yours probably went bad.

Take the amp to a tech to have it looked at.

Yep, unfortunately that seems to be a common failure mode with those amps. Trying to get it repaired may prove quite frustrating, and perhaps not worth the time and money.

Is this a common problem on all of the Crate V series amps?

No, not all of them.

From memory, I believe the earlier made in USA (St. Louis Music) incarnations had standard power transformers. The later made in Vietnam models seem to be the ones that started displaying major reliability problems. Only these later versions of the amps had the switching power supplies.

The V series up to the V32 ,whether made in the US or Vietnam were OK. Standard PT and power supply . After the sale (I believe) to Loud Technologies Crate amps went downhill with the introduction of the V33 and its switching power supply,different circuits,etc. Bob
