What year is this Ampeg B-15N?

Late '67 -70's. Speaker says 1967. You'll need to open the chassis and look at the date codes on the pots, starting with 137 followed by the year and week of year.

 

I think the speaker says 70, if I’m reading it right. 137 7007, the last digit seems faint, but early 70 speaker would fit with the pots and PEC modules being ~mid 1970.

 

I bought one of those brand new somewhere around 1980. I'm one of the rare people who like the sound of those as much if not more than the 60's amps..

 

Yes you’re right, my bad eyes...Thanks. I see 34th week of 70 on the PEC tone module. From the codes, it was probably manufactured in the summer of 1970.

The head looks all original which is wonderful!

 

Looks like a good one. If the price is right, snag that baby!

Oops...I guess you already did

 

Every amp that I’ve bought in California had one of those orange stickers.

 

Nice find! Congrats.

 

She's a beauty

 

Nice! I've had 4 B15's, and the best was one just like yours.

 

I think the most precise way to know the made year is to take to some center where ampeg gear is being made. Yes, it is pretty difficult, but if You really need this - it's the only way. As to schematics - internet.

 

Unless you live near Calabasas CA, not so easy for most. And even they can't tell you how to date certain eras of Ampeg gear as the info was disposed of a long time ago. Some eras, however, are easily dated by serial. This one isn't, so you use part codes to guess.

 

Congrats

 

I use Autosol metal polish, you might find it locally at Walmart or a car supply place, otherwise https://www.leevalley.com/en-ca/sho...shing/67014-autosol-metal-polish?item=54Z1510

Wow.... sure looks like a very well preserved example.
Great snag!
