I need some help to both identifying (kitnumber not printed on circuitboard) and getting manuals for some of the old (20+years old) velleman kits.
First, i have a 60W amplifier module, approx. 8x20cm, with a MJ2501/MJ3001 output transistor pair. The module is in working order, but there is 2 trimpots i’d like to know how to adjust, so a manual would be appreciated. 
The other kit is a 2x16led vu-meter, which misses the ic’s… If i remember correctly, it should have UAA170 ic’s, but i’m not sure… Also, i seems to remember that i had some problems with this kit adding noise to the sound when connected to an preamp… (?!)
Can anyone help me out?
At least the adjusting procedure for the 60W amp would be appreciated. 
Regards…
