Mackie PA amp, mixer, and 15” EV speakers

Mackie M-1200 Power Amp - Usually when first turned on one channel is scratchy or no audio until driven hard and then it works fine. I used to just “hey” into the mic loud a few times and it would start working. I had it fixed two or three times over the years but always came back so I just dealt with it. Mackie 1202 Mixer - Everything works good as far as I know. SKB hard case with pull out tray for the mixer - tray is a little rough in/out but works. EV S-152 speaker pair - both in good shape. Pair of 50’ or so speaker cables not in good shape but work! Pair of patch cables between mixer and amp. I’ve owned this setup for 25-30 years. Has been in my rehearsal spaces for most of it. Finally replaced with new stuff so wanted to pass this on to a younger band.
