I have often been wondering why have the match problem of two 4CX800 tubes?
Would it not be better to always use one 4cx1600B tube? Of course the latter
tube will easier generate parasitics because its ability to amplify at
higher frequencies than the 4CX800.
By the way, when is SVETLANA coming out with a direct replacement of the
3-500Z? There has been rumours of a 3-600Z tube, I heard. Since EIMAC
stopped manufacturing the tube it is very difficult to find anything similar
reliable on the market. I recently saw a HENRY 2K3 with the original
graphite 3-500Zs from early sixties in good shape.
Why buy SVETLANA 3cx800s when EIMAC has a much longer manufacturing
experience? The very small price difference does not motivate buying
SVETLANA. Or is their quality higher?
Is there, by the way, a reliable source for 3CX1000A7s with sockets?
