more information

Primaluna Prologue Two amp has gone mental again, i.e. broken down

It's the same problem as before where one or more output valves start
glowing on and off like buggery, loudspeakers drivers being thrown fully
out and back again, loud pops. this is happening with or without music
playing


Dave, Peter's come up with a pretty through investigation procedure and I'm
sure he'd get to the bottom of it, but if I were you I'd just run it in to a
repair tech unless you're confident about fettling it. Contact your seller
first? Also, is there a warranty running on it?

(I've got Phil's Ming Da here and these Chinese amps are pretty well
stuffed - not like a bit of homebrew with plenty of space to play about in!)

Thanks for the vote of confidence. Like most basic diagnostics, it
takes longer to write it out than to actually do it. I get VERY
squirrelly about visiting suggestions on other's equipment remotely
until I have a very good understanding of both the nature of the beast
and its proper behavior. So it drives me nuts when I am presented with:
"I have this amp, it doesn't work.... Any ideas?

Apologies to Dave are in order and herewith tendered.

That will be the 'completist' in you, but no bad thing!

I believe Dave's amp is quite new and almost certainly still in warranty (?)
which is why I suggested he might follow the 'take it back to shop' route.
(Stuffed, it was an eBay Chinese amp, of course!! ;-)

As we are crossposted, let's bring the RATs up to speed on my 2 Chinese 300B
SETs:

Amp No. 2 - little used, perfect behaviour and now gone - snatched away by
an EL34 PP user after he heard it!! (??)

Amp No. 1 - thrashed mercilessly, volume pot went on the fritz (replacement
was promised but never arrived), WW2 Chinese military driver valve fizzing
and had to be replaced, fragile/spindly lead on a (Boer War) German
capacitor broke and has had to be resoldered. Otherwise, still goes like a
train - OK, possibly a bit more Western Pacific than Western Electric, but I
love it and use it all the time!!
