Keeping track of everything is getting to be hard work. I've been recapping all the ST power supplies I have. List goes like this;

Mitsumi SR98 x 2
ASPF34-4 x1
Tokin x1
DVE DSP-508A x1

The DVE is the only one I could get HV caps for locally. Its working a treat now. Interestingly the supplies with the most visible problems are the Mitsumi's. They looked atrocious when I pulled them out. One of them had a bulge in the 47uf 400v cap and the rest on both had leaked.

I decided to check the MegaST PSU's while I was at it. The two I have had ASPF34-4 PSU's. I decided to give the ASPF out of the big button 1040 a crack in the Mega and low and behold it worked. I'll look into that a bit more. One of the ASPF supplies is a rev 6 and has C3 installed.

I wasn't a recap skeptic, but was always figured if it ain't broke.... well, most of these PSU's had leaky caps. Its worth doing.

With so many ST's I'm still recapping seemingly ad infinitum. Also taken on an A600 and Vampire for a mate which means I'm looking at recapping a couple of A500 PSU's too. It's getting right out of hand.

I picked up another STE motherboard and PSU so I now have two in need of cases. Not sure how this keeps happening.....

On a happier note, the Aussie summer is great for retro whitening ST's and keyboards. I've had a few yellowed ones that are now back to white. It seems to take about three days on average with good results just after one day. I have a couple of stubborn ones but I will persist. At least they now look grey rather than yellow.

Fixed a pile of spare keyboards too. Slowly winning and the repair pile is getting smaller by the day.
