Is it worth refurbishing my tube Marantz?

The Marantz equipment is currently at L&M Electronic Service Co (the only long time shop that repairs and refurbishes this equipment in the Bay Area).It will cost me $500.00 to refurbish the Amp. I know at one time these were in demand but I've no idea how to sell it. The equipment, as identified below would be in perfect working order. The Pre Amp serial number is 7C &-19051 and the Amplifier's serial number is 8B-8-7286.

This equipment was my fathers and has been carefully stored all these years. Any feedback would be enormously helpful as I have to come up with an answer soon.

In addition I have my own 1969 JBL SA660 solid state amplifier: serial number is 7194.

If you plan to sell it you are probably better off selling it without rebuilding and let the new owner deal with that issue.
Great point. Depending on what is done during the refurb, the compromised originality that may result could easily reduce value considerably more than the performance improvement might increase it.

Also, be aware that with highly collectable pieces such as the Marantz tube models, cosmetic condition will often affect value to a much greater degree than functional condition.

It will always make sence as it will have value as longs as vacuume tubes are available.
For some reason with absense of good quality semiconductors, the vintage solid state electronics are completely devalued while tube units still have due to the parts availability.

In any case look at the tubes inside. Sid used the telefunken ecc803s in many of these and the tubes inside may match the value of the 7C.

Ancient equipment is only a collectors play, not really meant for actually listening. The classic ancient designs have found their way into modern knocks off, Cayin and VAS does many of these, and does them well with SOTA parts. So, if you want to actual listen, take that route.

Buconero117,
I believe that modern valve designs are not advanced to the vintage ones. Practically no difference in at least performance. The only difference is PRICE.
Vintage units such as HH Scott, Fisher and Marantz can bring same level of performance for much less.
