Okay so now I have been listening to my resurrected R-900 for a few days and have found a few things that could use some improvement. I am looking for a few suggestions...
Issue 1)
I can hear the radio a very low volume when the input is on Aux, Tape 1 or Tape2. It is not very loud but is audible and gets more audible as the volume is turned all the way up. Tape 1 has the most interference. The phone input has no radio noise, but hums instead. I have done an internal cleaning and sprayed and worked the all the controls including the input selector with Deoxit and lubed them afterward. I cleaned up the dust off the boards gently. What should I do next? Try cleaning again? Any area to concentrate on?
Issue 2)
Preset station buttons have a hard time retaining memory even when not unplugged some #1 holds, but the others are iffy. Thoughts? would changing the original battery out help?
Issue 3)
Weak FM reception on some stations. I would like to get fm 98.1, but it barely locks on and still has quite a bit of hiss type noise. A few other local stations can be crystal clear example 95.9 and 93.5. I am using a 6 foot ribbon cable type T-antenna mounted inside on the wall. I tried rotating it around but there is no change. The transmitter tower is about 4 miles away on the tallest building in the city and I live at the top of a hill, so I should be getting an excellent signal.
My brand new RX-A730 brings in this station perfectly using only the cheesy dipole wire that came with the unit and is hap-hazardly pulled through the cabinet and stuck to the back of a speaker.
I am thinking a longer ribbon cable antenna mounted outside may do the trick, but finding ribbon cable is difficult. I guess it is not the 1960s anymore.
Should I do some more cleaning? Do I need a super involved tuner re-alignment? Would weak caps be the cause of all my issues?
On the plus side I have teamed up this unit with my circa 1990 Tannoy C-8s with newly refurbished surrounds. First time speaker repair for me. Stone Roses - Fools Gold rocks, I can feel the drums in my chest at less than 3 on the volume.
