Hello, I have a problem with Creek Destiny, the fuses (3,15A) on the power input are blowing. A short circuit does not blow the fuses (10A). What could have been damaged.
Hi,
Did fuses in both channels blow? If only one channel then you can isolate the issue.
Usually a blown fuse is caused by a short while powering the amp.
I haven’t had a fuse blow after the amp warms up. Did the fuses blow when turning on the amp, or after the amp warmed up?

Hello, Gregory I burnt one channel, I looked for the fault with a meter, I checked SR101 and SR 102 with a meter in diode mode. And I think I damaged LM336M.5.0 with the meter because now the fuses ( F205 and F206 3.15A) are blowing.
The LED (Standby is on) But when I turn on the amplifier the LED goes off and They burn out F205,F206 .This fault does not blow the fuses (T10A ).
I see. If one channel is bad then it should have blown F201 F202, or F203 F204. Are F201-204 are okay? My guess is F20x has the wrong type of fuse and did not blow in time to protect F205 and F206.
To see if the right channel is bad. I would remove the fuses F201 and F202. Then check if the amp turns on without blowing F205 and F206. if it does turn on then you’ve isolated the issue to the right channel.
I’ve damaged lm336-5.0 a few times from accidentally shorting to ground.
Did you diode test SR101 and SR102 with the power off or on?
I would diode test SR1 vs SR101 and SR2 vs SR102 to check.
Next diode test the IRL2910s from drain to drain.

Hi Dariusz,
The relay may also be damaged. Can you check resistance across the relay coil? I should be around 60Ohms. That might explain why the F205 and F206 are blown.
Are F201-F204 ok?
Can you diode check SR101 against SR1 and SR102 against SR2 across pins 4 to 5, 4 to 8 and 5 to 8? If they’re all the same then the lm336-5 devices are okay.

Can you send a photo of RL201A Schrack RP8?
