Biggest problem are passwords, i remember everyone i ever used, but knowing which one is the latest is a bummer.

It's like toiletpaper in the supermarket, 50 different types and brands but not a clue which one to buy.
(i know a few who bring their 1 & only along when they go transcontinental. trans-incontinental ?)

Jacco,
Don't confuse members to use toiletpaper instead of mica or kapton. and vice versa...

Is the "1 and only" the same as "the 1 that must be odey'd"

Hugo,

i was just about to mention that i found toiletpaper with the lowest thermal resistance.
And it's dead cheap, a roll will last a lifetime. Userfriendly, cut and paste job.
(it seems environmentalist researchers have even been experimenting with some kind of ecological thermal grease)

NP still favors mica.
Shaving mica insulators thinner is really easy with an oldfashioned raisorblade.(also named CocaCola blade)
Consider using Aluminium Oxide insulators.

thanks again for the responses!

i'm almost there in terms of BOM... one last thing (i hope) to ask:

i've been looking for a toroidal transfo over at rs and farnell, but the best one i could find is a clairtronic 300VA 18V one. Will this be enough? I read in other posts that recommended is around 400-500VA.

thanks!

Since the amp draws a constant 200W, 400VA would be recommended.
Or, if you can afford it, buy two transformers and make separate supplies for each channel.

hi guys,

me again

i've shopped around for heatsinks and the best one i can find is .3 C/W (measures ar 300x300x40).

ambient temps where i live would be around 25 - 30 C.

this would put operating temp at 55 - 60C. is this feasible for the F1 or would i need to augment the heatsink? (thinking of some fans for a bit of active cooling)

thanks!
