You should be able to figur that out but first read the instructions they contain some amazing information. I can not help you because I have no idea of what you are asking.

If you're able to switch between them then your issue is possibly relay, relay driver or microprocessor related; all of which require a service techs attention. hope this helps. Gene

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

Can you please provide more information about what you mean by "refresh"? Is there a performance problem or funcitonal problem with the unit?

Thanks,

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.

try switching cables from one channel to the other and see if the problem follows the cables.

first check your speaker cabels for short circuit and speaker for  short coil .after you confirm there is no shotr of cabel wires by checking with avometer in ohm postion.connect speaker if the problem excit your speaker is guilty - change it with same configuration.about switches put it in low order and chech for sound level and you can go up after that.

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

try subbing out another newer speaker for the left one ? if sound returns then that older speaker is defective .

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.
