Default Why cheap Chinese amps are not the chopping block for high-end tube amps

Though I started this thread, I don't actually know what size the amp
is that Keith lent you. The big issue in tube amps is matching the tube
with the speaker through the transformer: output impedance, damping
factor, sensitiviity/volume and transient overload ability.



The amp Ray is trying is the very Dynavox featured on this page:

At around the 250 quid mark on eBay (inc shipping) from German sellers (no
VAT) I reckon they represent the very best introduction to valves you could
get for the money. They are plain but well-built and very substantial. I
have a number of correspondents who have got them and one or two have
started tweaking them.

The valves in the ones Ray's got are some old, very mellow 5881s which I
suspect are slipping nicely down into the comfort zone. I'm thinking I
should maybe have left the original Chinese EL34s in it to better 'compete'
with the powerful ss amp he is using...???

He preferred the 5881s when he heard them both here but that. as you say,
was on my speakers....
