Any one have this schematic. Trying to trouble shoot this amp.
Thanks

Re: Bogner Metropolis
A search on this forum should pull up a thread where Larry (aka novosibir) posted some specs about this amp.
Good luck,
Stephan

Re: Bogner Metropolis
I saw the info but not very much help. Would still need the schematic.

Re: Bogner Metropolis
I would not mind posting a schematic it since the amp is now discontinued from production but I don't have a schematic of this amp. Yet I thought that there is a lot of valuable information in this thread: http://forum.metroamp.com/viewtopic.php ... is#p269129
You have the topology which is paralleled sections of V1, into schizo switch and gain pot, then V2 wired as a direct coupled cathode follower, tone section, reverb, PI. My guess is that PI and power amp are Vox AC 15 values. The tone control section is probably AC30 top boost. I would not be surprised if the values used around V2 are also AC30 top boost.
The B+ for the EL84s should be around 320-330V.
You said in your first post that you are trying to trouble shoot this amp. What exactly is your trouble with this amp - does it not work or doesn't it sound the way you want it?
Cheers Stephan
