A friend of mine has a HB 4X1. The supply runs 4800 at idle and under load
drops down to 4200. On 160 to 20 he gets 1500 out with full drive from his
TS-850, or about 110 watts. This is a GG design. Power starts to taper off
on 17 meters, where he gets around 1400. 15 is down to around 1300 and 12
and 10 are around 1250 to 1200 or so. This amp has the glass window that
lets you see the tube and let me tell you, when the rim is dimly lit it
looks fantastic when you peer through that glass window and see that tube.
There have been a lot of 4X1s on ebay lately, unfortunately, most of them
are sold "unchecked" from dealers so it is a gamble.
