MARANTZ MODEL 10 TUBE AMP/ TUNER AND MARANTZ 7 TUBE PREAMP


Hello,
I am about to acquire Marantz model 10 tube amp (NOT 10B) and Marantz 7 tube preamp. The amp is very rare because they made only 100 of them and I've seen one on Ebay for 13k for sale and it is from Europe. Does anybody know the value of these? They are also rack mounted so I think that makes them even more special. Any suggestions will be appreciated .

Have they been refurbished? If not, I would only plug them in long enough to see that they light up; any longer than that and the power transformers are at risk due to failing filter capacitors in the power supplies.
If they have been refurbished, what sort of warranty do you have? The power transformers will likely have to be re-manufactured should one fail, which is not cheap.
