Thank you for the help....Today, 03:27 AM -
Hi All,
Anyone out there did any fault finding on the above amp with no reverb. I suspect the spring reverb tank is faulty but want confirmation before ordering a new one. Scoped that audio is present at the i/p to the tank (sinewave gets distorted when the tank is connected). I also injected a tone on the o/p of the tank which I can hear on the amps speaker.
Any advice appreciated. -
As a lot of older firmware images use the well known, incredibly secure AMI XOR key to encode the supervisor password in the firmware image, I wrote a small Python tool to automate the process of searching through the image and decrypting the key. It is far from perfect but works well enough for me to share.
The tool uses UEFIExtract to dump the entire image, naively search for a folder ending in "AMITSEDecrypt", iterate through the body.bin to find all possible hashes stored in there, decrypt them with the XOR key, remove every second byte, then convert to ASCII.

I'm looking for some help, sorting out a protection circuit fault on my Kenwood KA-701 integrated amp. The amp does turn on , but the relay don't click. It usually ends up being, a transistor, or cap on the protection circuit, DC offset problem. I can't read schematics real well, and the ones I have are really bad quality. There are no good quality one's I have found so far. Looking for some professional help. Blue Midnight helped me a lot in the laptop forums, but It's been a few yrs, like 6 or so. I don't even know if he's on here or if anyone does the amps, but any help navigating throught... -
