Hi Every one,

Have been busy on the resistor - found the 47 ohm resistor - has gone open as suggested. Bought new 47 ohm resistor and replaced. Thurned amp on and voila....... many many thanks I cant tell you how greatful I am. I love this amp.

I will keep track of your mods, thought to be honest they are beyond my current abilities.


All the very best!!

Re: PM66SE

Hey Guys,

Me is new here too, been surfing for a while now and the only thing constructive on Marantz PM66 is here.

So I got a Marantz PM66SE, which has a big offset in the right channel and a lot of cracking when turning up the volume. Is someone familiar with this problem and the fixing part?

The other channel sounds better but I have to turn up the volume a lot to get some action.

Stupid me lent it to a nephew (young) which had a big party..... So overheating should probably be the cause.

All help would be great!!!!

Thx & Cheers,
Reinoud

Firstly I would flip the amp over and cut out the removable plate. Have a look around for a dry joint.
Also try the cd player in to a different input (IE AUX) as you may have a dry on the cd input.

Hi,

This is my lightly modded PM66 KI-S. It's amazing what you can get them to do ;)

Is that still classed as a PM66

Nice work though. What are the main details of this mate?

It says PM66 on the front.

It's probably still got as many original parts as your CD player!


:D

Seriously, though. It's a couple of ZAppulse modules and sidewinder PSU (all from LC audio) hooked up to a 450va toroid. It should be putting out about 200w per channel.

When I had my CD63 KI modded I decided I needed some more amplifier to do it justice and I wanted to keep the matching look in the rack!

Regards

Pete

Looks very nice, is that class D amplification?

How does it compare to the unmodded Marantz amp??

Hi SImon,

Yes, it's Class D.

Compared to the PM66 it's a lot more detailed. There were a few changes to the CD player around the same time so a bit of the improvement may be down to that. Basically there just seems to be more of everything.

Well it's been a while since I modded my amp as i've been working on mains cables and filters.

Yesterday whilst wondering about a bigger VA tx the penny dropped and I remembered I had a spare KI tx.

Here is the result....

An externally hosted image should be here but it was not working when we last tested it.
