K7PEH> You would need a cooling fan in their for a 20 to 25 amp supply and I don't think the P3 is set up to handle a fan.
My RS-20M doesn't have or need a cooling fan (though that's in part due to its venting and heat sink, so that needs to be carried over to the P3 enclousre). I'm going to see if I can migrate it to the P3 (which itself probably doesn't generate a lot of heat). If it needs one, fans are small and can sit right on top of the case, fed with 12 V from the supply that will now reside inside. AC7AC> And much of that space in the P3 is reserved for P3 add-ons that are in development. I expect I'll be so happy when my bare bones P3 arrives that I'll live with it as-is for a while. If I'm tempted to fill out the inside with add-ons, I'll remove the supply at that time and figure out Plan B. AC7AC> I rather like the idea of an external power supply. It doesn't need to occupy table-top space; mine sits on a box under the desk. Same here - but I'd like it more if it matched the P3 enclosure. And now it might... This may be too ambitious but I'll give it a shot and won't be too proud to say "you can say you told me so" if I fail. If it's too much of a stretch to fit a 20 A supply in there, I'll use a supply of less than 20 A, and settle for running less than 100 watts from the K3. When I get a KPA500 sometime in the (distant?) future, I'm sure the stepped-down K3 would still have plenty drive to run the amp at a level acceptable for my needs. Really wish I could just buy a blank P3 enclosure and save all the trouble. --Andrew, NV1B ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
