[jleaman]

well i just tried my new set of fred's for my blue amplifiers they sound a little cleaner. But i didnt know that you have to have them on heat sink. and after a few min i guess they got hot and well BANG!! heh. here is my picture.

Well, you should be always carefull when working with electricity. When starting a new circuit for the first time, I always wear glasses, as you never know what can explode. I also try to monitor temp on semis and capacitors initially, by touching them carefully. If you did that you might had prevented the loss.

BTW, I once had an accident, when a capacitor exploded into my eye. That made me paranoid about capacitors and that's why I always wear glasses when checking new circuits. I also have only one real pupil left, as I carry a plastic lense in my left eye for the last 20 years.

How's that jam, for being carefull and aware?

i'm the same way when i plug things in i use a piece of plexy glass to hide behind. : O )

i really didn't know i needed to have these Fred's on a heat sink .. or this would not have happened.

 

[jleaman]

Now i need to get more . : O )

 

[Peter Daniel]

Are those the ones from me? I can send you more if you need. Just give me the part #.

 

[jleaman]

if your going to send more. : O )

can you send me one of them thick isolation pads used for the irfp244's ect ect ect 's

i want to see one.

please..

 

[Peter Daniel]

OK. How many diodes?

 

[jleaman]

I don't mean to be a mooch peter. but long time ago you built some nice rectifier boards for your a40's i believe.

you used 8 Fred's and 8 of them green caps. do you have any of those left. maybe send me one or 2 so i can order more. i would like to try some out. ?

and 4 Fred's is good enough as i still have 4 Fred's right now..

And do i need isolation pads to mount these to a heat sink? of can they just be mounted to the raw heat-sink. ?
