I haven't operated an Acom, but note that it uses 4cx800's (as do a few other companies). Those have been discontinued, and not having a future source of tubes could be a concern. That's why Alpha switched the tube in its 8400 from 4cx800's to a 4cx1000's (new model is an 8410).
The THP is a nice amp, but bear in mind that solid state amps are more sensitive to SWR issues than tube amps. If you don't have good resonant antennas, a tuner may be essential. I also found that the THP 1.5 required 100 watts plus from my K3 to drive it to full or close to full power, whereas my PW-1 and Alpha 87A required a lot less for full output. If I were looking for a non auto-tune tube amp, I'd seriously consider the Alpha 8410, perhaps one that uses 3-500Z's (inexpensive and readily available). Not sure where I'd go on an autotune tube or a solid state amp, other than what I'm currently using. 73, Lou >I am thinking about a move up in power for my K2/100.
