Hi, I have a marantz LV-520 that I picked up to use as a parts unit(I have another unit in slightly better condition that I use normally). The machine would not power on, so I replaced the fuse, and cut out the k1v452 arc supressor. The machine is working now, but I'm trying to find a replacement part. I've heard k1v26 is the replacement part, and pioneer stocks it, but for $24. No one else seems to have it, but I did find some similar items. Do you know if K1V24(W)-4060, K1V26-7060, or K1V26-4060 would be a suitable replacement since they are much easier to find? I ordered one of each while getting the fuses, just in case they would work.
Also, I'm having issues with side b on certain discs and trying to realign the bar on the top portion of the machine. I've heard the only way to get this exact is with an oscilloscope and a calibration disc. I have a traditional analog oscilloscope, but I haven't found much info on the disc. Is there any way to obtain one, or am I better off just fiddling with it until it works?
Sorry for the block of text, and thanks in advance for any help!
