Has anybody any experience of dealing with the removal of this white gunk.I think I read somewhere that back in the day it’s use was thought to be a protective measure .Is the removal a diy task...thanks Dee

Where is the white gunk? Could you post a picture?

Also noticed that the main board has been cracked .. does anybody know if this is repairable or do I need a replacement

Is the white gunk heatsink compound? In which case leave well alone as this ensures a good thermal connection between components and the heatsinks.

The "cracked" PCB looks too regular in shape to be damaged, is it not a separate section by design?

White gunk is as already said heatsink compound, this does not need to be removed.

Where you see the crack? This is the pcb for the receiver for the remote and supposed to be like that.

The one I've got here if I remember correctly replaced 4 resistors as they are underpowered and recapped it, again if I remember 3 out of 4 of the large psu caps measured well under spec

R.e the original problem, I doubt that you would find an replacement volume pot that will fit properly. And it certainly doesn't need a new knob, this has no bearing on anything than making it easy to turn the shaft easily and to make things look nice.

What I would do first would be buy some deoxit D5 and try cleaning again. If you look at the side of the pot on the black square bits there are some access holes, aim the straw and spray the cleaner in there, rotate the pot fully 25 times then spray again rotate a further 10 times then leave to dry then try it out.

Hi Chris! I was the guy that passed on my ailing E100 to you, exactly 12 months ago to the day! Hope you managed to make it well again. I was going to suggest Dee contact you for information regarding his amp, but unfortunately I'd forgotten your name

It's crap when your memory starts to fail, luckily I've had a lifetime to get used to that

Hi Steve,

Again thanks for the amp,

Yes I got it going, there was two under spec'd resistors in each channel which made the traces in that area of the board very brittle, luckily there was just enough pads/traces to anchor replacements to. Whilst the main board was out I recapped it with spares I had laying around, quite a few caps were out of spec and some of the big psu caps rattled when I removed them they were that dried out.

My memory isn't what it used to be either and find that I have to write things like this down to remember properly.
