Got this kit built 18 water recently. The guy I got it from was clueless as to who built it much less who made the kit. It's got a 20" chassis and the only one I've been to determine as having this size chassis is Trinity. This was built in 2013, does this look like a Trinity amp kit? What schematics would match it? And are there any gurus who can help figure out a slow pulsing going on in the background on this amp. Thanks in advance.

Ok looking at the pic I decided to check online and see what GDSwould turn up. OK it’s not a Trinity. Still looking for help on the pulsing.

Some sort of 18watt TMB with a plexi flare would be my guess. don't now who's layout it is . But I do see the phase invierter as the second tube .

Theres may layouts for this.

This. looks like its close to yours except for the the firs two cathodes res/cap being reversed. http://site.triodestore.com/18WTMB.pdf


As for you pulsing issue is it in both channels volume up down ?

Yeah, probably that's the one. Nice layout but the order of the tubes in that design was always bad as was the location of the MV but Trinity changed all that!
