[R-390] General valuation?

Don, Property has changed ownership in the last 20 years.Doing a catalogue of what you have nearly put one of the old R390 part sources into an early grave.Aggregation exceeds return on investment. All the R390 R390/A manuals and thirty plus years of collected wisdom are at R390.net All the readers please ask for what you need.Our readers ask what about this. this gets a written response. Ask about parts. That request will get you a one off offer from some one.Aggregation exceeds return on investment.The cost of the postage exceeds the cost of the parts and time to get it in the mail. So what ever happens is between buyer and seller and the U S Mail man. Don you could marry a frame and wire harness from Fair Radiowith all your modules, do a paint job on one front panel andthe receiver maintenance and listen to it for the rest of your life. The other threads are well supported for taking the time to do one for your self. It is a project and the art has many usesand stories that will carry on for years of enjoyment even ifit just setting quietly in near memory. Laundry mat service time to get to a clean machine to start will cost $1,000.00to sub contract. A week on the patio table across a warm week and do it your self. Software audio from the diode load had made the receivers the the new band converters between technologies again. Don, when you get to it. You will look up the parts you needto makes some repairs. Once you get past stock tubes, resistors,caps and hardware available on line.  Then ask for the clamp, slug, crystals, or even whole sub decks if you need one.The price is not free. What ever is agreed to is a steel and we all know it. We give the parts away not our time today. Roger AI4NI    -----Original Message-----

Hello from a new member to the list.  I guess I should say returning 
former member, as I was on this list many years ago.  I sent a reply to 
Roger only by accident, so will try to put it on the list the right way now.

I wish we would see R-390A equipment/parts listed on here from time to 
time, especially parts available.  A "parts donor" or even better might 
be in the offing if I could find one close and in reasonable shape.   I 
am bringing back up two radios that have been down for a while, and will 
likely need some help from the list as well as a part or two along the 
way.  Ebay prices on the parts are still a bit ridiculous and small 
parts (clamps, Oldham couplers, etc) non existent there or seemingly 
from Fair Radio anymore.  One of these receivers is in very good shape, 
just not run for too long and the other had a previous owner that 
butchered sections to "improve" things, so it will be a long process of 
putting back right.

I appreciate all the work done in the past, and those that contributed 
to that work.  More knowledge available than can be easily and quickly 
read!!  Nice work though and helpful.
Thanks all,
Don, WB5HAK

A Saturday afternoon activity once a year as you do an oil change and wash. One AC / DC volt meter a special spline wrench and long #1 Philip screw driver will troubleshoot any electronic problem in the receivers. You eye ball the gear train andyou do own a military clean machine where dirt is friction.  R390/A are receivers that ran 24 7 for six months. 4380 hours between maintenance activates.On time to warm up time of tubes is if the tube is on for more than two hours Tubes will fail emissions before the filament opens from thermal cycling. Turning the receiversoff and on will not change tube life or performance. The whole receivers do well to warm up and stabilize before going on air. About one a year the Amateur Owner needs to do 8 hours of cleaning, lubricatingand alignment of the receiver. Do wash the front panel and pin strip knobs on occasion.It is a four hour job but that's not the way we move it. Tube life is over 10,000 hours. R390/A are mechanical and need all the knobs exercised to keep the receivershappy. Yea you need to pet the things to keep them purring. Every dollar under 500 is how well was the last PM doneand how long ago in operating hours. If you move any R390/A in and out of a rack / cabinet  it incurs theexact same mechanical vibration risk and will notcare how long it was since last thumping by gravity stopped. Transportation cost exceeded anchor value.Nice 400 - 500 dollar receivers are setting because the cost of relocation is an equal cost. There are receivers available but the entire Amateur market for the R390 and R390/Aover the last 30 years has not supported a central pool. Fair Radio Sales in Lima Ohiokeeps parts but has given up R390 receiver sales because cost to ship exceeds product value.Drive to Lima and spend a day shopping in an electronics logistics depot.Look in your R390 parts manual for part numbers when ordering parts.The company catalog  is not the R390 or R390/A parts manual any more. The receivers are still best on the Planet and doing well.Their value is holding and no end of parts is in sight. Receiver less meters is under 300 and with acceptable replacements at 300. Respectfully, Roger Ruszkowski AI4NI-----Original Message-----
