Old Veronica 25watt amplifier needs schematic

Fmtx · Post by **Fmtx** » Sat Oct 22, 2016 12:08 pm

Hi everyone ,I have here a old Veronica 25watt .which has a problem as to the person who had this has missing components and which case It also has components snipped with the looks of things on it .
Problem I have here is I can't seem to find a old Veronica 25watt schematic with component list to resolve it to working again ,if any one has a spare copy would be good or even a picture of it in close up would maybe help .mean time here's a picture of it .it was made 2001 it says on the Veronica board !!!!

All I can see missing is a fuse

The one i send you is this one i am sure and i have also seen this amplifier picture but i dont remmeber where .Also diode 1n4148 is broken near the yellow led for detection

That picture is one I just took no long ago ,yea the diode is knackered and I replaced it .but I took the fuse out as it keeps popping the fuse .green light comes on but once a start adjusting the blue trimmer the fuse blows. Also the small coil on top right has broken off I just need schematic cause I'm in doubt if it got to the transistor leg box or were it is situated as its loose at moment .

Here is the updated fix . But unsure if that coil should be at top right .something is telling me that is right cause I'm sure my old Veronica 30 watt in a box had that there but I can't mind was back in 2090 before I sold it .

2090 meant 2000 sorry predictive text there !!!!

Input and output only needs 1watt to run this .

My old 30 watt Veronica with the sane amplifier but trouble is it's a bit blurr to focus on the layout .but that's what I need a closer look but this one is not clear enough .

The amp in your pictures has different output matching to the schematics which have been posted. There is an extra matching section in your amp (copper 2t coil to ground and capacitors coming out from the collector of 2N6084).
If the fuse is blowing when you turn the trimmer, are you saying the amp is working but drawing too much current? Is the correct fuse installed? Have you got the output correctly connected to a good antenna or dummy load?
