Level 1 Charger Plug...

Hello all. I tried to locate a chat room for this specifically but...this is the only thing that I\'ve found.

I\'m not electronically knowledgeable enough to know what to do so, here\'s my question;
I have a blown HER303 and I\'m wondering if I should replace it with a \"larger\" diode? I ask this since it looks like it stays pretty hot whenever energized.

Oh yea, this is a compact hard drive power supply.

Any help would be VERY appreciated.

Incredible! I was looking at a machine today going for 100 dollars.
Should I not buy it then? sorry i am 20 years too late to this thread.

Well, the group is still active, although the original thread
participants have likely moved on.

As all these units will be over 25 years old by now, it\'s likely they\'ll
either need maintenance or will already have been fixed up at some point
- check with the seller to see if they know if any work has already been
done on it. There\'s a discussion over on the Tapeheads forum that
describes most of the common faults:

You should probably at least count on having to replace the power supply
capacitors if this hasn\'t been done already. Any mains-powered
electronics from the 80s and 90s should ideally be checked for dried-up
smoothing capacitors in the PSU, as well as the infamous exploding RIFA
line-filter caps, and I think that goes double for a machine with known
power-supply reliability issues.

> I also was wondering if these machines can play PAL tapes? Thanks!

No mention of it in the manual, so I\'d assume not.

UPDATE: I really don\'t understand this depth of verbiage but, I found this post and would very much appreciate some \"seasoned guidance\".

This Mouser diode has both lower reverse recovery time and is rated for 4 Amps at 80C.

Why don\'t you exercise your google-foo and spend some meaningful time with your browser and FIND OUT ON YOUR OWN!!!

I put the radio together last night. I\'m listening to it right now.
It\'s nice to be able to \"see\" my bench again, and be done with this

difference in readings on the front end. I\'m not going to worry about
that or the exact bias point for that matter. I have all my notes and
that\'s a project for another day, (maybe). I\'m grateful that it\'s

You\'ll have to excuse me now though. I have to go build a garage, so
