OK, don't know about you lot but I'm just about done with checking here
to
find nothing doing, ..........


We're all too busy fixing the miriads of Chinese valve amps
that seem to have been dumped on Europe and Scandinavia:-)


'Miriads'....???

No-one's buying them then...??

;-)




I have a fixed bias PP amp on my bench that has 10mm
skeleton pots for bias adjustment.

The owner who imported it directly, told me that it
worked only at very low power when it arrived, so
thinking it had been damaged in transit, he took it
to a local TV repair chap. He soon found the problem,
there was, and never had been, no connection between
the bottom end of the OPT secondary and the ground
terminal:-(

It looks like there might be an opportunity for someone
repairing these amps on a regular basis, to make
good money. At least there is an assured constant supply
of work. The trouble is, you can't spend much more
than an hour max, or the repair has cost half of the price
of the amp:-)


Check my previous posts on the subject - I have always said to consider that
they might need a little attention from time to time and maybe not buy one
if you can't fettle it yourself!! Even paying some primadonna's price for an
hour's work to sort one out wouldn't make it cost a fraction of a 'Western'
price - how long before there are realistically-priced *specialists* in
Chinky amp repairs, if there's as many about as you claim?

(How Long?? Do you think he and Wun Hung Lo might start summat up? :-)

But what does it prove? Shiny Nigel's EAR 834P phono (same price as a Chinky
300B SET) went tits-up in about a week from brand new....



I have seen several of these now. They all bear a remarkable
similarity and have a generic PCB which can be used for
any number of different versions. Fiendishly cunning these
Chinese:-)


No PCB in my Chinky (which does play up occasionally) - all I have to do is
shove it in the cupboard for a few weeks and it usually comes out with a
better frame of mind on.....
