Does anyone have any info on these? I'm guessing they're some type of resistor bundle? Maybe not?

Oh dear! These haven't been made for a zillion years! I'm not saying you won't ever find replacements. After all, people do win lotteries. I'm just REAL glad it would be you looking and not me!Originally posted by lustandfury View Post
Anyhow, in the Golden Years of the 50's or so these things were quite common. They could hold both resistors and capacitors and often had a complicated circuit arrangement that would not be obvious from the outside. Your devices appear to be either axial lead resistors or caps wired straight from one side to the other. An ohmeter might help. If they are all resistors you'll find the values quickly. Caps will need a cap meter. If the wiring inside is not like it looks from the outside you're in trouble! Let's hope you get lucky!
Are you sure anything is wrong with them? They rarely fail. No sense in spinning your wheels in the least likely areas if you don't have to...
Now, that 50 uf 10 volt ancient electrolytic cap beside it should definitely be turfed! They dry up over the years, even on the shelf. A replacement will be a pittance the size and only a couple of nickels in cost. -
Thanks Wild Bill,
I've found a bit of info on the Erie Resistor company. They were the first to use injection molded plastics in North America. I'm just trying to map out this old Filmosound projector amp I have. I can't find a schematic for the 399 model that uses EL84 tubes like mine does. I guess they were only made for a short time for the North American market. And they are very different from the three 6v6 model 399 Filmosound schematics that are floating around the net.
I'm new to the whole tube amp game so it's been one hell of a time trying to figure out what's what in the amp. I want to convert it to a guitar amp like the "Bernie" filmosound amps. My next step is to replace the caps. But I'm thinking I might just gut the whole thing and start from scratch because some of the tubes aren't even needed for guitar amplification. Thanks for the help! Here's the rest of the mess...

So what is the amp, and what are the chances we have a schematic of it? That would tell you what is in the part. Chances are real good the part was made custom for that amp maker anywayEducation is what you're left with after you have forgotten what you have learned.Comment

It's from a Bell & Howell Filmosound model 399 projector. The only schematic I've found for it shows a version made with three 6v6 power tubes. Mine is a slightly rare model that uses an EF86, two 12AX7's, Two EL84 and a EZ81. They're completely different amps so the schematic doesn't help. I've had no luck trying to locate the proper schematic. Here's a thread with a bunch of discussion about Filmosound amps:
