I have another batch of these available....

If you have a Roland SH-101 with a dead Transformer (part reference T1), so a Roland SH-101 with no negative 9V rail or +21V supply then this is the module you need to get it up and working again.

I keep meaning to write up instructions for testing and confirming that T1 is dead, but as I do not have an SH-101 to hand cannot, however Col has written up his experiences including this helpful picture:

Also DJ fix has a Video including installing one of these:

If your SH-101 does have a dead transformer, I also strongly recommend you set up a bench supply to test it before ordering one of these modules.

This will need soldering skills to install, but uses the existing rectifiers to avoid the likelihood of further damage.
The first picture is what you get, 1 module (assembled and tested) and printed instructions of how to install it.
The other three pictures show the prototype installed in a Roland SH-101
