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.

Hi my Korg SP170S digital piano has just stopped dead no light, no power and now won't switch on.
First things to check, power supply unit, is it the original or the one that has previously worked - if yes check the output voltage with a meter to ensure this is working.
When you plug this into the piano if you wobble the plug does the socket feel loose? You may even get a tempoary connection, if you do or it feels loose the socket needs repairing.
If this all checks out ok the next step is move inside the piano, you will need to know a bit about electronics to proceed to this step.
Report back and I may be able to help further.

Frender frontman212r has a huming noise when
If the humming ONLY happens when a cable is plugged into the amp, the problem is in the cable or the guitar. Poor quality cables or wrong cables will result in hum. Defective wiring or connectors in the guitar OR having the guitar near a source of magnetic fields will result in hum. We cannot diagnose these possibilities remotely.
