Problem With the Power Supply for AKG SolidTube

The fuse blows out after one time.  I replace the fuse and I can record for half an hour or more, after that, the power supply shuts down.

    Thank you mike

    Could the mic cause troubles even though this sounds good? If so, Could it be the Tube? I made a test replacing the fuse 125ma (the power supply keeps on for 1 minute and blows out afterward) for one 250ma (the power supply keeps on but gets hot and shut down after a hour some times less time)

    Bought my new SolidTube in January 2008. Used it on three different days. After 10 minutes of warmup, I get no noticable sound level when singing into mic, although I can hear my voice very faintly, as if it's on another channel with the fader right down. Then....after 2, 5 10 0r 20 minutes...suddenly...there's the vocal ...!! Makes me crazy. Maybe the PSU is made by Behringer. I expect more for $1300...! Pete LeRoy Cape Town South Africa

Well your obviously drawing too much current.
The other given is that it takes time. This means its a thermal problem. Temperature goes up and current goes up with it.

Look for plastic or cold solder joints. A plastic joint is dull and brittle also look for islands in the solder joint where the solder
is actually disconnected from the part.

Components like regulators also can go thermal.
Look for discoloration.
Get the unit to act up and carefully spray freeze mist at
various locations and you may agrivate it.

Problem may be in MIC and not SUPPLY.

Good Luck

Crest audio ca4 blowing fuse

There is two possibillities to fuse blown off due to hi current flowing through fuse more than 3amp.because power supply componant like rectifying diode, filter capacitor or regulator ic ,regulator transistor shall be short circuited.
if you are tech......just remove amp. supply.from main power supply...try with another fuse........if fuse ok, fault is amp side, or if fuse blow off ...power side problem just....maximum fault comming on varistor ,diode, filter capacitor, .........
if you are not tech......... give to local authorised tech.......

I would be inclined check your +48v phantom power supply to make sure the correct voltage is coming out and to check your cable. Failing that, if you have changed the tube once I'd be inclined to contact AKG Directly via email to find a service center or get furthur advice.

My RCA DRC 8335 won't turn on, it justs keep saying "HELLO". What could be the problem? Have unpluged for more than 48 hours hoping it would reset it's self. DIDN'T. Was starting to have problems with it...

The problem is with a capacitor on the power supply that is too small and blows out. Its number c226 on the power supply, it is rated to be 16v, but that is too small. So all you have to do is go to radioshack or a store like that and get a replacement. I have fixed about ten of these systems and I found that it works best to use a 35v 470uf capacitor as the replacement. It costs about a dollar and a half. All you have to do is remove the power suply board find the capacitor number c226 and replace it with the bigger one. It is an easy fix that works great.

Sound Problem

What are you running this mic into ?, an interface mic pre ?, a soundcard ? A console/ mixer ?
Since this is a tube mic it should have its own power source and I am assuming you plug that in when using it ? Don't use phantom power on this mic, even though it's a condenser mic, since it's a tube mic wich have their own power supply you don't need phantom power on them and in fact it may damage its power supply.

AKG C535 microphones pop and hiss

if they are "condenser" mic's, the condensor module, as in the case of capacitor, failed as time goes. <condensor = capacitor>. Might be a good idea to check other capacitors inside.
