Hi, I would like to share with you my experience with PCB - Marshall, Valve PCB TSL100 / TSL122, Rev 20.
I couldn't find the product in Europe, so I ordered it here even at the cost of high shipping and import tax.
I had big problems with the original revision 5 board, which was already modified. The first channel was too noisy to be used. I replaced this board after a quick delivery and import costs were taken care of.
The amp cleaned up beautifully and is one of the best sounding tube amps I have had the opportunity to try. Although this is purely subjective. This amp also has overheating issues, I solved that by installing a grille on top of the amp. According to the link below

The amp sounds like new, I've tested it at several band rehearsals and it has been put through the rigors of public performance.
I recommend it to all amps that do not have revision 20. It's worth it if you have these problems. On the internet this has been and is being addressed over and over but old records degrade.
It is expensive but if you like this amp it is one way to save it.

This board is a pretty easy install. Anyone who has an early TSL100 or 122 can safely install this board as long as they take the common sense precautions. This was my first time having to work on my amp since my TSL122 began to have the classic bias drift problem that these early versions of the amp get. It ended up blowing two of my power tubes and my T1A fuse. Marshall could not have made it easier to just replace the board itself, it may seem intimidating at first but there is another comment in this thread that details the map of the board to every connecting it needs to make, minus two that are only used with new lead circuit boards. If you don’t have it, don’t worry it works just fine not having those two plugged in, as well as W8. Definitely recommend this and anyone who is afraid to try this to fix their TSL, don’t be, it’s not that scary, just have common sense, patience, and confidence! You can do it!

Although the package showed up quickly and what seemed to be safely packed, there may have an opposite effect. There was so much packaging paper crammed in the box it squashed a lot of the parts such as the resisters , diodes..etc, together. I carefully separated them from touching each other anymore, but It makes me nervous that there may be damage to the board that cant be seen yet. So ....If its a good board, I'm excited to get my amp back up and running soon. So I'm going on faith that its all going to be okay. Besides, Ive ordered from Amplified parts before and they are excellent company and I'm sure they will take care of me of something isn't right.

Installed this in my 1998 JCM2000 TSL100 Head. Great product! Fixed the bias drift issue. Arrived safely due to it being well packed. Fast shipping!

The install is pretty straightforward. I recommend you document the layout connections before you install. I found this to double check my connections.
