Fisher 1800 Receiver Information thread and roll call

Ah, so the 1800 and 800C face plates were in fact physically different (besides the bottom coloring process), if only to accommodate the emblem. Still, you have to imagine that all the face plates started out as 800C pieces, and were then modified as needed to become 1800 face plates.

If I remember correctly, the indent was pressed in, not machined and shows a bump out on the back side.
 
My 1800 has no raised edge where the darker color starts, with my eyes closed I feel no transition from the bottom brown section to the silver top, it is totally smooth.
Here is a detail, it is anodized:

I'm not sure of the anodizing process, but wondered if it would be difficult to do it on just one section. Very possible they are all just silk screened, and some needed repaired. If you look close on the 1800 in question, there is a small drip of white under the lettering.
 
I tried the fingernail test, perhaps there is the very thinest of a lip, but it is really hard to detect, almost nil.
I am not a metallurgist, so I don't know about the masking process involved with anodizing only one section of a piece of metal. But I am a printer by trade, and in my humble opinion, my faceplate is not printed with a transparent brown silkscreen ink. Depending on the light in the room, it reflects light from different angles, as anodized surfaces do. When you look from below it is darker brown, look at it from above, it is lighter brown. From side to side it changes it in character also. Silkscreen surfaces are more uniform in tonality from the physical layer of ink, and do not reflect light in the same manner as anodized surfaces do.
 
if it's established the earlier units were anodized, even if they did have the indentations there could have been spares made up without any markings...leading to the painted/indented later units. has any one seen an 1800 *without* the indentation? looking at the pictures the earlier, "anodized" ones seem to have the model indicator screened on flat rather than a plaque set in an indentation (how it appears in pics). iirc early solid state fishers had the same indent/plaque, and were painted/screened, not anodized.

I have one of the earliest serial numbers, and one of the later with no difference. The one on the auction site is fairly early so no timeline has been established. I'm leaning towards them being replacements.
 
Here are mine minus my first unit which is in a wood case and lurking else ware. These all look dark in this picture with poor lighting, just curious if digital pictures are causing the confusion.

There is something else I noticed about this latest 1800 that is on the auction site, seems that the normal tan colored can capacitor is black on this unit. That's the first time I have seen a different one on any 1800 documented. :idea:

Just thought I'd add to this thread with documentation on the manuals for 1800 receivers. Looks like they used 800-C manuals and box, then added a decal on the box stating a 1800, and adding a note on the manuals that they also cover the 1800.

By the way, I believe you are correct in the above post--that looks like my 1800 (and its box).

Mine is in the listening room doing duty for FM reception right now. My Dave Gillespie-special 400 is getting a rest right now!
 
I just finished completely restoring my all original 1800 that came with box and manuals. The original tubes were only getting up to .20v for bias, installed a trimmer and they didn't really go up much. Ordered new quad of Tung Sols.
 
I found an interesting addendum among the 1800 paper work I was looking through, never noticed it before and thought I'd share. Looks to be directions for switching operating voltage.

Another interesting find, looks like the assembler of this 1800 left an extra power transformer nut wedged in the corner and pinched under the other. Should I leave it for originality? :D
