Peavey classic 50 chassis removal

Theory works, plan not so much.

I hooked up a lead to the power switch.

I used the ground from the plug ground prong. There were probably easier grounds, but I do not know enough to come up with my own places for things as important as a ground. It was not easy to do. Note missing screw.

The loose green wire is my target.

Re-attached. See it way in the back!?

In the end, the plan failed. It does not fit in the cavity through the board. I hope this helps someone else.

So after all this, I have learned that noise and airflow simply go together. This has a stock a sleeve bearing fan as opposed to a ball bearing fan. Sleeve is the quieter of the 2. The airflow is "43" which is high (not sure of the quantity of air that the number indicates).

The stock fan that I have is Nidec TA300, E34399. This is a 24v, 80x80x25mm. I have attached a pdf for future reference.

I do, 2 of them ! But I no longer participate. The Peavey guys try their best to help and it is a valuable resource for Peavey. This forum is a valuable resource for everything. We are a knowledgeable bunch!
 
You know RVA if you play that 50 watt Peavey amp loud as its supposed to played at Club level you will never hear that fan.Just sayin:cheers:

So, I don't remember reading, how old is your amp approximately? They've been making those things since what, early 1990s (92ish)? The 2x12 that my buddy has is one of the very early ones(no fx loop).
I take it that it wasn't always as loud? Or are you just sick of the whooshing that it normally has?
I have really been noticing his as being louder these days. When he first brought it to the studio it could/would be left on accidentally(it sits on a 4x12 cab so you can't easily see the light-until I turn out the last light in the room...then I would see the red glow on the ceiling.). Now, there is no "forgetting" it's on. It is fairly audible. I presume if the bearing isn't beginning to fail, it needs to be disassembled and cleaned out.

You are 100% right. I did not purchase wisely for my needs. That is why I offered to sell it rather than junk it. It sounds great (but like a great Peavey - it does not sound like a Fender). If you play at band practice volumes or louder, the fan will not bother you. But I sit next to the thing with volume on 1.5 and it sounds like the landscaper is outside with a leaf blower!

Less than a year old with about 20 hours on it. It could only get worse from here!!!!

The truth is that the fan moves a lot of air - it has every right to be loud.
 
Its a common mistake there RVA to buy the big watt amps for in the house.Its like ,oh i cant get Pete Townsends Live at Leeds sound.Well he wasnt playing some mythical beasts he was playin a SG and those big old amps cranked up to concert levels and thats where they shine.I mean lets face it even a 50 watter in the house cranked is not gonna be a pleasant experience.Now a smaller tube amp cranked in the house ,well you get the picture.

Wow! We put 20 hours on his every 3 months...if we're not gigging...but we do play fairly loud...especially him.
I had my reservations when I found out there was a fan in there. I understand they're milking the 50watt rating out of a tube set that would be normally used in a 30watt circuit...but...a fan?!?! It's not my amp.
I run my 18watt , and have no problem keeping up.
15-30watts seem sufficient to me for most applications. Hell 5watts gets pretty loud. My 50+Watt amps don't get too much exercise these days.
