[R-390] NIB tubes

I hesitate to post this query to the list but I figure some of you may 
be able to help and/or might be interested...

I have come across a small quantity of NIB tubes that were part of stock 
from a '60's vintage RCA TV transmitter and would like to determine a 
*fair* price for these tubes. I would prefer to sell them to someone 
with a use for them in an R-390 or some other glowing gear rather than 
going to eBay! The tubes are listed below with number/manufacturer 
(quantity):

6AC7/National (5); 6AG7/National (2); 6AH6/GE (5); 6AK5/National (2); 
6C4/GE (5); 6V6/RCA-JAN (4); 6V6/RCA (2); 5670/GE (5); 6146W/GE-JAN (2)

I have not crossed the 5670 so I don't know for sure what it is except 
that it is a short 9-pin miniature tube.

Any help in determining what the tubes are worth would be appreciated.

I am also in a position, financially, where I may have to sell the 
R-390A that I recently acquired and I would like determine a *fair* 
price for it...no, not an eBay-based price but one that would be paid by 
a real collector and not a "middleperson", although what I have seen in 
the recent thread here does make me drool ;>)

The receiver came in a case with the shock-mount base for mobile 
operation. The front name plate has been removed and the panel has 
silk-screened lettering which is all in very nice condition. The front 
panel is a bit dirty but not scratched or damaged to any significant 
degree, except for where rack screws were installed. Both line level and 
carrier level meters are in place and seem to work.

Inside the receiver is very clean on the underside and a little dirty on 
top, but not excessively so. The band change and tuning mechanisms 
obviously could use some TLC but they work fine. The old line cord was 
very brittle so I replaced it with another cord to verify that the 
receiver works...it does but needs alignment.

On the rear panel the unbalanced antenna input connector is damaged with 
half of the center-pin fingers missing. There are five empty holes on 
the rear panel...two are unmarked and just below the antenna connectors 
and a larger hole just below those two marked "Sync Xtal Osc" with two 
small holes just to the left of that legend.

That's as complete and honest a description as I can provide at this point.

Any suggestions as to the probable value of this receiver would be 
appreciated. I am going to try my best to keep the R-390A but only time 
will tell!

73,

Jack, AE7DX
