KAT88 low output from right channel

[KTea88]

Guy's your help please.
I have a KAT88 and I fired it up the other day to find that the right channel was at a very low output.
I checked it was'nt the input to the amp swapped the L/R inputs still the same.
swapped all the valves L to R still the same.
then I turned the wick up on the pre and if by magic the Right came back ok.
I havent opened it up yet. I suspect a dry joint.
I left it a few days and again the same problem low output on right.
and again winding the wick up cured it.

But you guys might know if a component is on the way out and point me in the right direction before I go chasing my tail etc.

I've been there also. I'd also suspect dry joint first.

Best wishes,

Greg

Try poking the joints with an insulated stick of some kind on very low volume and see if you can find a dry joint by that means,

its probably in some part like a HT feed/ anode load resistor, as it gets hot it expands a little thus disturbing its position a lttle, try the input stage first, intermitant faults can be a pig to find, but perserverance pays off, any how let us know how you get on.

Guy's,
Just to let you know all sorted, not sure what it was re wetted any joints that looked suspect.
