Hi All,
I've become the very happy owner of a Bogner Shiva Combo, however, I have noticed that it has started "clicking" upon power-up from cold, it sounds like a bunch of relays getting juiced up, this only happens on 1st switch on/cold, and once its happened once, it will behave fine until it lies idle/off for about an hour, where it will then do it again (as if something is draining charge)
When it happens (when amp switched from off to Stdby)the amp (or what sounds like relays) will click/stutter for a few seconds and then the amp lights will light and the amp works/sounds fine from there-on
I have spoken with Bogner, and they have suggested that I replace the Valve Heater Power Supply, but before I delve in to the innards to replace, has anyone else come across this before, and is replacing this power supply ( which I have ordered and received btw) a pain in the arse to do?

thanks mate, thats what has apparently landed on my doorstep today with a 8 quid UPS admin charge (bought from US!!)
Are these PSU's known for this behaviour?
OK, had the amp in bits and with the chassis out I can see/hear that this clicking noise is coming from nowhere near the Heater Supply....there is an LED on the Supply board which flickers in time with the clicks...reluctant to the change Heater supply if it doesn't need changing..
Time for a tech? or am I just being picky as the amp works fine after its powered up

So you guys think I should replace the heater P/S? its only 2 solder points from what I can see (they have bypassed the plug-in connection and hard wired it)

Sorry for the constant q's guys, this heater supply has a trimpot on it but I can't see/understand what it does, do I need to worry about this or is it a case of setting it location-wise in the same setting as the old one?
