Is it worth refurbishing my tube Marantz?

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.

They are beautiful pieces and yes if they do nice work I recommend you get them fixed. The filter caps in the preamp and the amp will need to be replaced. The selenium rectifier on the preamp will need to be replaced as well. The output transformers on the 8B are some of the best. They were designed by the late Sid Smith.

Forget what these guys are saying, just give them to me.

Seriously these are great investments to keep, if like you say they were looked after and carefully stored, they could be in great condition. BUT!!! I would not just plug them in and switch them on.

These could be in great condition component wise . As they have been in storage for a long time I would get someone who knows what their doing to bring them both on very slowly from (monitoring a few parameters like bias etc) 0vac to full mains 110volts going back to 0 every 20 volts over a period of an hour or so till you get to 110vac, using a big arse variac.

This will slowly condition things, mainly the capacitors, and even the tubes to a degree. Instead of giving everything a shock with full mains volts instantly.

Or like I said you could just give them to me.

Cheers George

When your Marantz pieces come back from L&M, put them up on an auction on Audiogon or Ebay. I'm sure you'll be very pleased at the response. Don't worry, you'll recover your $500!
