My Ampeg B-15S

[knarleybass]

I have had this amp for a while, it sounds good but to be honest I have never really used it. Can anyone give me any information about this model and perhaps help me figure out the year it was made?

Looks like between 71 and 74, made by Ampeg while they were owned by Selmer. They're very hard to date by the serial number alone, but by looking at the speaker code and the code of the pots, you can get an idea. The B-15S is a slightly higher powered version of the B-15N, with 60w of RMS power and a solid state rectifier instead of the tube rec in the B-15N. Great amp, dude!

The tubes say Magnivox, could they be the original tubes?

sick amp

Most definitely. Selmer was owned by Magnavox for a while. They are more than likely Sylvanias relabeled by Magnavox.

Looks like mine.

but to be honest I have never really used it.

What do you mean?

I have one here in MA with Magnavox tubes in it also and they still sound good. Great sounding amps but make an SVT seem like a lightweight. Mine has white rocker switches and no polarity switch making it a later 70's amp. I would say early to mid 70's is about right. Those are original tubes. Mine is also rated at 60 WRMS but they are rated conservatively like all old Ampegs were and mine's pretty loud. Make sure you have the switch set to 8 ohms for one cab. Those are not real common either, I'd hold on to it.

Thanks for the info, I was looking at the back label and it says that Ampeg is a division of the Magnivox company, That would explain the tubes. It's one heavy amp I must say.

According to this website...

...the black control graphics on the amp with square corners make it a 72-75 model. If the Ampeg logo on the cab is metal, it's a 72. If the logo is plastic, it's a 73-75.

I've found that if I carry the head in separate from the cab its not so bad.

Not to hijack this thread, but what year is a B15N with blue graphics and an Altec 421 speaker?

 

[JimmyM]

Blue graphics mean it's probably between 68 and 70.
