solid work horse

I'm a owner of the ME 1500-V for 2 years with additional LED bars for Pout GridTemp/Reflecter Power and so on. This version also has some additional protections. After I got my PA I had problems caused by inner arc of the tube. Gabi changed tube for free and since them the PA is running perfect on JT65b/FSK441 and 24 hours contests. The Pout max I measured is max 1200 watts and at digi modes stable 950 watts. Pout is also depending on your line voltage 230V - if you have less also Pout is a bit lower I measured. The GS35b tube is not getting very hot but I added also a 2.fan at tube blow out.
At all I'm absolutely happy with the PA and I won't miss it in a pileup.

Solid, Reliable, Best Value

I have been a happy user of the ME1500V for about 4 months. Since I removed it from its packing, I have been regularly stressing it almost daily with 1 KW of JT65b carrier for 1-2 hours, in other words, I use it like I hate it!. This is a realy rugged amp, just give it a good ventilation, low VSWR, push it slightly under its rated power, and you can expect many years of trouble free VHF operations.

The grid area is critical. The grid has two jobs, to shield hf and to shield from dirt and dust. If flys or spiders with long legs are sucked in by the fan, the legs can reach the stripe line and make an hf short circuit with the result that the grid-gaze burns away.
So it is heavily recommend to place a second grid to prevent dust and insects. The build in papst fan must get airfree from the outside, so to place a second grid between fan and backside of the pa. For this operation you only have to put away the fan and replace it with grid. It is easy, cause the nuts are fixed with the core. After this the protection is perfect.

Best bang for the buck

A series of very nice VHF Amplifiers with different kind of tubes are built by HA1YA. I bought a ME1500-V with a GS35B tube. Price for a GS35B at german flea market is about 80 EUR, so you can get easily a backup tube an have fun with the amp.
The finish looks professional and mechanical work is very good. Different protection systems: warm up, overload Ia, Ig1, VSWR, makes operation safe.
Gabi, HA1YA uses for different types of amplifieres the same mechanical hf cage. Normaly the GS35B does not fit into this cage. Gabiīs trick i to shorten the cooling section of the tube.
The cooling section of the tube is big enough to stand this brutal operation.
With an input power about 100 watts the GS35B gives 1.35 KW output carrier in this amplifier. HV is with 2.6 KV a little less for this tube. The HV is rather stable. Small disadvatage of this HV configuration might bee, that you have to run a lot of current to get the output, higher voltage would be smarter.
The ME1500V has an build in sequencer with a delay abt 200 ms after pushing ptt.
Conclusion: I am very satisfied with this amplifier, itīs nice tech and itīs money worth.

Input SWR: typ. <1.5 (var)
