Marantz 4140 quadraphonic amplifier

I can get a Marantz 4140 quadraphonic amplifier in good condition, at a fair price. Unfortunately I know nothing about it and there does not seem to be much info on the internet either.

Can anyone tell me if it is a good amp? What does it sound like? Is it durable and what is to be expected of the old capacitors? Will they need replacing or can I just leave them in?

I own a 4140 and like it very much. The two big reasons it is not my everyday amp is that it is too powerful for my 1 bd duplex, and I want to wait to use it until after I have completely recapped it so it is reliable. I plan to pair it with a 2270 (also in limbo for the same reasons) and get 70 x 4. I am currently using a 2440 with a 2216 combo; 2440 has been recapped and 2216 the cap list is being built.

I think general consensus on this forum is to do a complete recap for reliability sake.
 
Hi mcsew2k

Thanks for the information. I am going to have a look at the amp tomorrow. The guy wants $350 for it. I am keen on the amp, but I am not too sure if I am in the mood to recap.

I think $350 is a good price for a working, but unrestored 4140; at least it is where I am. I will be recapping mine this summer.
