1. [Amps] Combiners for SS amps + cooling issues. (score: 1): Author: "Jim Thomson" <jim.thom@telus.net>; Date: Thu, 12 Sep 2013 06:06:34 -0700; OM Power makes a combiner to handle up to THREE of their amps. I believe its rated for 5 kw CCS. On the subject of cooling....or say water / liquid cooling, I would think that Freon would be the idea; /archives//html/Amps/2013-09/msg00068.html (8,058 bytes)

(score: 1): Author: "Leigh Turner" <invertech@frontierisp.net.au>; Date: Sat, 14 Sep 2013 15:35:27 +0930; In answer to your question Jim, my favourite RF power MOSFET today for HF linear SSB amplifier use is the VRF2933 devices from Microsemi. They have a VDD drain breakdown rating of 170V which means op; /archives//html/Amps/2013-09/msg00156.html (9,335 bytes)

(score: 1): Author: Bill Turner <dezrat1242@yahoo.com>; Date: Sat, 14 Sep 2013 19:49:06 -0700; ORIGINAL MESSAGE: (may be snipped) REPLY: If the bridge rectifier is feeding a large capacitor directly, shouldn't that be enough protection against transients? I'm no expert on power line transients; /archives//html/Amps/2013-09/msg00175.html (8,096 bytes)

The problem with filter capacitors is their relatively large series inductance-ESL. Since most diode killers are fast rising transients, of relatively short duratio; /archives//html/Amps/2013-09/msg00180.html (9,499 bytes)
