just perfect  Time owned: more than 12 months
got that ZZ-750 for 3 years by now , with daily operation , it is a real workinghorse without any problems , solid quality , couldn`t be better and moreover you get that quality for a very reasonable price as well ,the GU 47 b is almost unbreakable !
it replaced my 811 from Ameritron which gave me only problems with the 811 tubes as they never lasted long !

using the ZZ-750 now , no need to replace the tube any longer
buying the ZZ-750 was a good investment !

Worst buy ever  Time owned: 0 to 3 months
It came with one fuse holder and a pin of DC connector both broken. mA needle went full scale and tube becomes to heat, a DC problem from power supply that broke the tube. The HF relay broke in a week. Power supply refurbished from another device and lots of component are not new.

Amplifier ZZ750+50mhz  Time owned: 0 to 3 months
Good amplifier with all hf bands and 50MHz now on its latest version.
the knobs may be a little bit old school. but performance is very good 800 to 900 watts. for less than 700 euros vlad you provide a superb machine with a tube GU74B (4CX800A) tube used in many amplifiers hf as acom 1000 eltron ed1 but dividing the price by three. thank's vlad good job!
