The Model 50

The most common Premier Amp seems to be the Model 50. The earliest amp I've seen is a 1947 model and I have one dated 1965. The model changed over the years, so here are the pictures

1948 Premier Model 50. I got these pictures off of Ebay.Original Rola 8" speaker, 285840. Tubes are 6SL7, 7C5, and 7Y4. The tubes are Automobile Radio tubes!

This Model 50 is just like one of mine. Notice that it assembled upside down from the way the 1948 was assembled.

Here's one off of eBay that might be earlier than 1947. It uses a 7F7 tube, but the rest of the tubes weren't listed.


I have three model 50's, all different. The oldest one is from the 1940's and has a low serial number. I would guess that this is one of the earliest Premiers.

It also has the original amp cover. This is something that I've never seen anywhere else!

This next one is a 1958 model 50 with a 12AX7, 6V6 and 6x4 rectifier

Here's a Model 50 off of eBay (I cleaned up the images considerably). The gold woven grill cloth is similar to a 1959 model that I saw. The 12AX7 tube visible in the chassis shot pretty much precludes a 1940's model. I am guessing that this is a 1958-1961 model with replacement knobs. All premiers of this configuration had colored knobs.

This is my Model 50 from the mid 1960's. It is square with the plastic letters.

Someone sketched out the Schematic to the Model 50 above, but I have seen at least 5 configurations for the amp. This combination uses a solid state power supply so it I guess it's well into the sixties. pic I have one like this. The 7591 tube provides as much or more power than the 6L6's in the earlier models. The tubes are not easy to find at junk stores and flea markets, though.

My best harp amp is a model 50 from the late 50's or early 60's. It has the 12AX7 tube and a 6V6 with a 5Y3 rectifier tube. This is the best sounding amp that I have ever played through. It needs to be mic'ed through the PA. I am setting up a rig so I can play through this amp with a mic from the speaker going to my Blues Deluxe. This is way too much equipment, but at least I'll be heard. The amp cost $35 at a garage sale. It has been partially repainted flesh tone pink for some mysterious reason. The grill cloth was kicked in by a drunk, but the speaker survived.

 

Here is an OEM Premier under the Tempo name. Obviously a premier model 50 with a cool guitar cutout, but still the catalin knobs. I am guessing from 1950.

Here is an even older Tempo from an eBay sale. It's in sorry shape, but the amp is on the bottom shelf and it dates from around 1948. The brown knobs also date it before 1950.

 

Buy the Book!

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.
