Hmm, is this legal in North America? https://qrznow.com/om4001a-om-power-amflifier-4-kw/ Looks fully-featured though, and it still has those lovely glowing glass bottles inside. _____________________

I forgot to mention, I own an OM Power 2000A+, uses a single FU728F tube. 2300W into the dummy load, no problem. 15W drive on 160m gives me legal power, typically 20-25W on most other bands, and it h

And those FU728F tubes are junk. It is all but impossible to get a good one these days. The supply has completely dried up. I would not touch an amplifier that uses that tube. 73, Alek, VK6APK On 24/

Right good points Paul, I especially like that the OM 2000A+ has 6m, and that it can be controlled via Ethernet.. Loads of reserve for digital modes for sure. No plans beyond the 2000A+ here, plus th

The main one is that you cannot get a good new tube in this country. Horror stories abound of people spending hundreds of dollars again and again, only to have tubes fail in very short order. Even on

Never heard of the FU728F. My concern would be that it vanishes like the 4CX1600. Interesting about the failures. I guess the type number is telling. Say "FU" out loud. Rob K5UJ _____________________

Isn't the FU728 the tubes used in recent Alpha Amplifiers? They are listing the tubes as 4CX1500B but I thought they were using Chinese tubes. W9DP Get BlueMail for Android __________________________
