Krell FPB300 When hot there is a noise coming inside the amp but not affectinng the sound

I have a Krell FPB 300 amplifier use to power my martin logan SL3 speakers. When the amp is about 1.5 hours running you will hear noise coming from inside the amp sounds like a small motor( the amp has no fan) but when you stop playing music and idle it it will lower the sound and when you put music back it will be there again, and it does not affect the sound.But on the first hour there is no noise at all. Please give some advise.

Hi There WLAW,
I am in Auckland NZ and do repair work for a high quality Amplifier chain so I could have a look at yours for you....

Being Local in Auckland it will save you sending it away off shore to Australia.

SOURCE: Hi, Will the krell kav 500i work on 220v 50hz

If it has a voltage selector for 220v, once configured it will work just fine Being electronic instead of mechanical the power frequency won't affect it. If it doesn't have a voltage selctor, don't plug it into 220.

Where can I get a fuse for my Krell KSA 300 amplifier.I had a blown fuse on the left channel.


Fuses rarely go on their own. The cause is likely to be a shorted semiconductor device in the left channel output.
Fuses are generally not specific to any brand. Is the fuse a tube with metal ends? If it is measure the length in MM. Then look at the end and you should see the rating. Either in A for Amps or MA for milliamps.
Any electronic parts supplier should have the one you want in stock. Buy several, for if the part I mentioned has gone, it will blow again.

How do I brigde a krell show case amp from 5 channels to three channels


Thai will require removal of the top cover to move jumpers or program dip switches in proper order. This will be explained in the owners manual which is located at Krells web site.

Hi, I have to replace all the 20 transistor of my krell kst-100 power amplifier- wich are the best choice? model and company? maybe mj21195g and 6 from onsemi?


Onsemi ( which is motorola) is a good pic for replacements If youre looking at the 21195 , then there must be a compliment to that as well? 21194 or 21196

Hello, after plugging on Ipod through my preamp hooked through my krell kav 300 integrated amp I heard a super loud noise and lost power. I examined the fuse and it looks fine. What do I do?


Sounds like the volume was way up when the iPod turned on. iPods are DC and cause a sudden thump through the speakers when they power on.
If the fuse is not blown, there may be another fuse you have not seen. Most amps have three to five fuses especially a 150watt/channel like the Krell.

Wiring Diagram required


At this point you may have fried the output stage. Is there a specific model listed on the back? I need that to locate the schematic.

Thanks,

That is an extremely odd problem. I suggest finding a tech in your area who is familiar with the unit, or contacting krell directly.
