So I'm at the very end with just a few odd things left. I have some wires I need to unwrap and re-wrap/solder because of corrosion. I didn't see the itty bitty board for the main bank of switches with it's four or five caps so I need to pull the tone board out. again.. and do that plus clean up those switches. Thats about it
Things done
All new caps on EVERY board I've seen "recapped" Marantzs for sale but they skip the AM/FM tuner board. Shame because on the 2285B, the FM tuner rocks it with a good antenna.
All new power transistors in the power amp module
New diode arrays in power supply
New relay
New LED lighting
A redo of the two massive dual stage caps to some perfboard mounts with four separate caps
A replacement of two of the big pots for DC bias/idle current with custom made mounting boards for precision pots. I was able to salvage two of the old pots after desoldering them and giving them a very good scrubbing in DEOxit cleaner and fader lube.
The four 2SC1345s on the tuner board were replaced with 1845s ( very black legs and noisy)
Scrubbed, cleaned, rusty transformer was cleaned and repainted, new sticker for the top ( Special thanks to
wlhd1610 for the decal) etc.
I painted the inside of the lamp housing white which really helped the overall lighting effect.
This Marantz sounds really good so far. I'm going to put it to the test with dummy loads and run it up as part of the final check. FM rocks.. AUX works well..
When this is done, I have the OEM wooden box for it to redo. I'm looking at redoing the veneer with rosewood or the like. Structurally the case is in great shape. It's just chipped to hell
I call this a rebuilt Marantz, not restored because of some the changes I did without regard to keeping the original look ( like the main filter caps)
