If you Google on the name you'll find lots of information - including schematics if you look around a bit.
That looks to be a pretty standard MONO amp - and puts out around 20 watts.
If it's actually working, and it's been run recently, then it's probably safe to turn on.
If it HASN'T been run in a while, then there's a good chance the power supply filter capacitors are bad, and will need to be replaced.
If it's been run recently, and doesn't make a significant amount of hum, then it's probably OK.
(Note that vintage amps generally aren't as quiet as modern ones - so a little bit of hiss, and maybe a tiny bit of hum, is normal.)
If it HASN'T been run for a while it would be a good idea to have it looked at before trying to use it.
(If the caps are weak, they could fail after a few minutes, or a few hours, make a lot of smoke, and take other components with them.)
I would also note something important - which applies to all vintage amps, especially tube amps, and especially integrated amps.
Different models tend to each have a distinctive sound.
Therefore, if you have any intention of using it as part of a stereo pair, you want to find it a mate of the same exact model.
Also, DO NOT assume that the amp will be at all flat when the knobs are set in the center - or at the mark.
(This simply wasn't much of a concern with vintage amps.... and it may not be especially flat at any setting, or its flattest setting may not be at the center.)
I would also suggest grounding the chassis.... connecting an actual wire from a chassis screw to a water pipe or outlet ground screw.
Vintage amps often have enough leakage here or there to actually give you a shock if you touch the chassis and ground (which will make you jump and isn't good for other equipment).
I'll give you a few things to be careful about....
1)
Watch the plates on the output tubes carefully.....
They should remain grey... and perhaps the tiniest bit of dull red in a darkened room.
If the plates turn very red, you must TURN IT OFF IMMEDIATELY and seek service.
The two tubes in the output pair should be about equal... if only one turns red then you absolutely have a problem.
This can be caused by a bad tube or a bias problem.
Bias problems are VERY common on vintage amps - and are relatively simple and cheap to diagnose and fix.
However, if the tube plates reach bright orange, they can be ruined very quickly.... and big tubes are expensive.
2)
DO NOT run the amp with tubes removed... even the little ones.
Many vintage amps rely on the tubes themselves to control the power supply voltage by loading it down.
On some amps, if you try to run them with some tubes removed, certain voltages will rise dangerously, which can burn out the power supply.
(This is real... I've done it...
)
3)
DO NOT crank the amp all the way up with no speakers or other load connected.
Tube amps can actually be damaged badly if you make them clip heavily without a load attached.
4)
TUBES GET HOT.... especially the big ones.... especially the output tubes and the rectifier.
We're talking hot enough to take the skin off your fingers without even feeling it.
This is normal... just don't touch the tubes after they've been on and don't leave it unattended around children or pets.
(How hot the tubes get will depend on a lot of things... some can be touched, carefully, others can light a match.... just be careful.)
5)
Finally.... There are LETHAL voltages under the chassis (more lethal than a wall outlet).
DO NOT open it up while it's running or run it with the bottom cover off unless you know exactly what you're doing.
And, yes, there are some parts that will hold enough charge to give you a nasty shock even when it's unplugged.
If you're not sure, it's a good idea to leave it unplugged at least ten minutes before touching anything underneath.
My friend gave a a working Bell 2200c integrated mono amp. It's missing the knobs but everyrhing works (he thinks).
I attached some pics .. the one with the knobs is what it should look like.
(Face plate is missing which identifies what each knob controls .
Looks to be early 1950s era product fron what Ive gathered online.
Does anyone know much about vintage stuff like this? Is there a place it can be sent to to test it out and fix anything that needs fixing?
It does power up and the tubes light up.. but that's all I know for now.
