thanks neil!
yes, the shield was touching the bolt, i lifted it, but haven't tried the amp yet. could that have been the cause of the noise? and yes, i will definitely add a shrink wrap here, i thought so too when i recognised this.
HELP!! strange noise!!

Re: HELP!! strange noise!!
Ok, i fixed the shield of the ppimv and couple other solderjoints, without any results. Anyone else got an idea? Otherwise i'll take it to an amp-tech, seems that this is the only option left then.
Thanks

Re: HELP!! strange noise!!
so... after getting the power tubes changed, everything works... seems that my other pair EL34 wasn't workin well too. i'd better get some spare-tubes, €160 for getting a new pair tung-sol EL34 installed...
anyway, everything works quite nice right now again, and i'm happy with that. thanks everyone who was tryin to help me out!!

Number 1 rule in a valve amp:
If it is not working properly sub in some different known good valves first
