A good amplifier Time Owned: more than 12 months.
Jerry at TOPTEK normally uses a 3SK97 GaAsFET in his 2m and 70cm amplifier preamp circuits. I used to supply him extra-low noise MGF-1302 GaAsFETs for fitment into his higher RF output 2m and UHF linear amplifiers some years ago as he couldn't obtain those devices in Taiwan.

Dependable little amp for UHF Time Owned: 6 to 12 months.
I picked up a Toptek PA-65U together with an Icom IC-302 from a ham in Maine last year on eBay. This was my reintroduction to 70cm SSB/CW weak signal work. The PA-65U as I received it provides 65W out for 3W in at 432MHz. I have no documentation so I can't say what kind of preamp circuit the amp has, but I do know that it does work. I've had some very good success with the old Icom portable and this amp despite a rather limited antenna. All in all I'm quite satisied with the PA-65U and only an upgrade of the 70cm station made me consider parting with it.
