In case anyone is interested, I've just put these up.

They show the insides of the amp.

Is that the amp's ventilated case it's sitting on? ;-)

Very pretty.

Very nice, especially for the price. I like the way they bothered to put the
component value prints on the pcb (for manual board stuffing?) and they
bothered to sleeve the wire of the two yellow caps but I wonder why they
floating so high ;-) maybe if its not wave soldered then it could be some
assembly workers overheated short leads with manual soldering :-) (there is
always a reason why) The pcb appears good grade as well. What sort of info
comes with the amp?

That looks like a stereo jobbie in which case what one is the mains
trannie and the O/P as one would expect two the same, unless their
contained in the large can at the back?....

Very nice Martin - I can see why you are enjoying it, even if I can't hear
it. Keep in mind those 6N5Ps have a rep for a tendancy to oscillation - see:

(I bet it's a hot little bugger in this weather though! ;-)

OK, I'll try and restrain myself.....

It is stereo. The Huge toroidal in the middle is the mains xformer.
There are (obviously, duhhh) 2 o/p xformers. One I left covered by the
can, and the other I "uncanned" and you can see in the photos. It's
not toroidal. They both sit near the back.

As for the heat shrink on the yellow caps, the reason it doesn't reach down
to the PCB is that I lifted it up. I was trying to check whether there was
continuity between those leads and some other points in the circuit. They
were originally right down to the PCB.

Thanks Mr Martin "toucans"......

Thanks Mr Martin "toucans"......

Two cans? ?

It's too damn hot sorry that went over my head i think.

off to the garden with a bottle of nice cold white wine.

I should be soldering my new resistors into it, but it's too
hot to use a valve amp now anyway! it will wait!

I agree - I sweated a bucket over my new amp, just ready to try out. That awful
moment when you hope to get sound out of it. Completely OTT layout on two tiers
of 19" racking - all brushed aluminium. Looks very industrial, which I like.

I am thinking of having one of these impotred off e-bay would you recommend
it? Is this model a push pull amp or class a?
