Hi my pm66se has just died on me so if anyone could send me the schematics i would be very gratful.

hi chris, i have taken a picture with my phone as my digicam decided to pack up today too .
There are two unused inputs on the primary which i suppose are the 110v inputs?
Would there be a fuse on these inputs which i could swap over i wonder. It looks hard to open up this thing.

Hi jakethemus,
The thermal fuse is in series with one winding. There should be two 120V windings in series for 240V operation (normally). With any luck you will find two terminals with thicker wire attached. These may be the thermal fuse. The terminals would measure open. You can bypass to check using a variac to confirm proper voltages. Do not just short and turn it on.
If this is a fault, you may be able to purchase a thermal fuse to reinsert inthe transformer winding. I do not reccomend running the unit without it. This also alows you to see if anything else is blown (like an output stage or rectifier). This means the unit may draw excessive current as you power it up. Use a variac.

Thanks chris.
I found the fuse and it was blown! 2A 150~C
Only problem is I have totally wrecked the transformer getting it out lol.
I could see no way of getting it out without breaking the damn thing. It was buried deep under the coils which are now wrecked.
Still I have learned something about transformers from this anyway!
My only hope now is to buy a new transformer, if anyone knows of a suitable replacement for this model please let me know.

eborgard said:secondary windings are 28.7V AC (which gives 38.4V after the bridge)
Is this the same for both sets of outputs of the transformer?
I need these schematics too.
Hi,
I need these schematics too.

Hi,
what a coincidence with this marantz... i have one broken and if someone can send it to me i will be grateful.
Thank you.

Hi all,
PM66SE here too, with a similar sounding problem to the original post.
If these schematics are still doing the rounds I'd appreciate a copy.
