Hi Guys,

Have a look here for a debug of this issue: YouTube - Ampeg SVT-5 Pro Problem YouTube - Ampeg SVT-5 Pro Problem
I recon two fixes are possible:

1. (Easy) increase the size of the heatsink on IC4.

2. (Hard) adjust the turn-on temperature of the fan by adjusting the control circuit.

I'm going to try 1, I'll let you know how I get on. my ampeg svt 5 pro - icon_tup.gif

Hi, I have an Ampeg SVT 450 head, and I noticed that it squeals every now and then.

Duberney, there's just no way of telling anything regarding a unit's condition without examining the unit, however, what you're describing sounds like something in the chassis (around the power sec) is loose. Duh. The procedure to chase that sucker down requires a technician to fool around in there with the power on, so it's really not something that I would recommend an amateur do. I'm sure you would have no accidents - but it's just plain fun to see other people get electrocuted. Send me your city - I'll find you a tech.

My buddy recently gave me his svt-6 pro amp head and there is barely any volume coming out of it when its cranked

Assuming you've tried other known working cables, speakers, and instruments, I'd suggest just taking it into a pro repair shop. If you start poking around inside without knowing what you're doing you risk frying the amp further or perhaps frying yourself.

Sounds like you have a loose connection. Try re-soldering the
internal connection. and check the wire for breaks. it may be the cause of your intermittence. Good Luck!!

Where can i get glass fuse for Ampeg 410hlf Mine is blown. It's the glass one for the tweeter

Radio Shack is usually a good bet, if there's one anywhere near you. Otherwise, go to their website, or check eBay and Amazon. If you can't find it there, you'll have to go to specialty electric/electronics vendors, like Shield's Electric or Graybar.

I use an SVT450H with the SVT410E and the SVT15E both 8 ohm Ampeg cabs. I have to have the main gain on 5 to 6 and the master volume on 7 to 8 and that is in smaller venues. I use a 1964 Fender Jazz Bass...

Check to see the phasing of the two cabinets and the cable. Take a 9 volt battery and touch it to the end of a cable that is plugged into the cabinet. The + of the battery has to be on the tip, and the - to the sleeve. See If the speakers move outward. Check each cabinet if they do then they ae in phase. Now try it with the second cable the results should be the same. If not and they move in the opposite direction then that cable is wired wrong. If one of the cabinets move in the opposite direction than the cabinet is wired wrong. You can also run one cabinet at a time if they sound louder by them selves that should also tell you that something is out of phase.

Sorry to read about your problem, I hope this helps you out.

the inlet valves just open and close, if you have high cold water pressure, it will override the hot water. I suggest you turn down the cold water valve, until warm is kinda warm. your cold water fills will take longer, but you will have warmer water
