I purchased my LA-1K and HF-AUTO at the same time and have been very happy with them.? They interface seamlessly using just the coax RF connection.? When changing bands, I usually (manually) put the Amplifier in standby (while the HF-Auto tunes), but that really isn’t necessary.? As explained previously, the Amp will automatically go “off line” due to SWR mismatch, allowing the tuner to find its new solution.

I run my LA-1K on 120 VAC and see SSB phone peaks over 1000 watts (without overdriving it).? I usually operate around 800+ watts.? It recently developed a problem and was returned to Palstar for warranty repair and upgrades (a manufacturing issue that affected some units).? I was treated wonderfully and the Amp was quickly repaired and returned in perfect condition.? From what I’ve seen, Palstar makes great products (in the USA) – don’t think you can go wrong with anything in their catalog.
