Mikes off! No recording!
i just bought a scott radio labs 16A metropolitan from a friend on AK. it was built in 1947.

the amplifier section is 12 tubes and the preamp/tuner is 16 tubes. this is one heavy all chromed SOB. the amp is in near perfect shape but the pre/tuner has a bit of rust but not that bad. i'll post up some picture as soon as i can.

I would love to find another matching 16A amp so i can use them as monoblocks. and build wood bases/cabinets for them.

right now they do not work. there is a cracked mica cap and a bulgding electrolytic so i'm going to have to replace all the caps. also the AC 120V input circuit is screwed up there is no plug/wire attached and someone did other modifications to it which are clearly out of order. if any one has the scematic please let me know.


Thanks!
Henry

E.H.Scott units are true collectibles. The bare chassis complete for the heavy chromed units can fetch some big bucks. You sure you want to do what you propose? Also, finding another amp on the cheap will be all but extremely difficult. Most know what they have and what they are worth. There is a dedicated group who buys and restores them as well as a dedicated site. I've not looked at the margue in several year but it was the holy grail of radio systems.
 
hehehe

Henry, I would do some serious research before I considered separating that pair. That radio is valuable.

I assume there's no cabinet? Not a problem, they were frequently sold separately from a cabinet. You could wait a lifetime trying to find another matching amp, unless you were willing to pay fair market value for it, which I'm guessing would change your plans pretty quickly!

Can't wait to see the pics!:yes:
 
You know, I was about to suggest that you check with Tom. He appears to have pretty much one of every schematic ever printed!
 
Suhweeet!!!!!!! got the schematic from a local friend. :D

the output transformer has a tap for both 16 ohm and 8 ohm speakers. also believe I found the amplifier input so converting it to a monoblock will not require any more modification than soldering an extra wire on for the input and speaker output. I will mount the speaker jacks, input jacks, and a power switch on the wood case when I build it.

pictures to be posted shortly. :banana:

btw, this amp uses (2) 6L6 amplifier tubes and (2) 5U4 rectifiers. also has a VR-150 voltage regulator on it which is quite different.
 
Basically an 800B minus the shortwave and motorized tuning, or so it appears at a glance. Much of that amplifier is actually the FM strip. That row of cans along the one end, and the tubes in between the cans are all FM IF, discriminator, and eliminator stages. The amp itself should consist of a 6SL7, the pair of 6L6 tubes, and the power supply circuit if its mostly the same as my 800B.
 
Still looking good, Henry. BTW, you need to thank me the next time we meet - I convinced Paul to buy the amp five minutes before one of biggest EBay flippers in town tried to steal it. The chrome, the COT faceplate, etc was all too much. :thmbsp:
 
I'd hate to spec one of those out today.Probably cost more than an Aston Martin:biggrin:

Mind you,on a positive note, all of the accountants and other assorted corporate bean-counters would all drop dead from heart attacks.....
 
That was actually EH Scott in the cost-cutting stage of their existence, and it was still very nice stuff. Their gear from the 30s was really a cost is no object sort of affair. The 1944 military issue one I have is so overbuilt its not even funny. Large boxes and plates around each section to keep the internal IF and oscillator from radiating back and acting like a homing beacon for subs. It works too, you can't sniff the oscillator in that thing at all. Most old tube gear will very easily broadcast the oscillator to anything in the room.
