Bill,

You might consider an OM2000A+ . This is an automatic no tune amplifier. https://www.om-power.com/products/om2000aplus

I looked on the OM Power web page and I don't see that they sell OM2000A's. The one they have listed is the OM2000A+ . Several guys in a past post mentioned this was a manually tuned amplifier which it's not.

The guys that own BeLoud.us use this amp at their remote stations. I think it's pretty reliable. There is also software available to control it remotely over the internet if you ever decided you wanted to do that at your station in V31.

Dave (G3WGN), Curious why you would need a KPA1500? I thought the power limit in the UK is 400 watts? Maybe I'm missing something?

Instead I added a second ACOM 2000A.  I have a very early one (1999) which has 
been beaten to cr*p when travelling to multiple big gun stations and doing 
loads of 48hr contests - it's never missed a beat.  Still on original tubes.  I 
do like the newer control box tho.
No experience with the KPA1500 but have been delighted with my KPA500 for many 
years and multiple 6Gs DXpeditions.
If a K4 is in my future, there may well be a KPA1500 to go with it.  At least 
the fan noise on the KPA1500 can be remoted from the operating position.

Looking for a backup amp for the new station.  Probably going to run SO2R so auto-tune is important.  
I'm running a K3S and the second radio will also be a K3S.  I really don't care if the amp 
"matches" the K3S in looks.  Like most of you guys I'm concerned about performance.  Both rigs 
are equal in price.
Here's the question:  If you were buying a new amp and were buying it to 
satisfy the above criteria, which would you choose and why?
