Hi guys got this one from a coworker to fix, downloaded a great service manual (major props to Mackie for actually wanting these to be fixed)
after testing I have a big list of replacement parts but had a question about the resistors on the base of the main transistors, about half of them are open. The SM specs them as 2.2 ohm .25 watt fusible and I am having a difficult time sourcing a replacement. Is it safe to use a regular metal film resistor in this instance?
Also one of the main filter caps has a reddish substance on the top that looks like it is leaking but seems to pass other tests, they are on back order until march. I'm not positive if its bad or not anyone seen similar leakage from these? I'm wondering as it doesn't look like the electrolyte I normally see leaking?
Parts list so far
r7, r13, r15, r29, r33, r34, r36
q28, q42, q15
d19, d20, d88, d89
c12
f4, f5
