Jbl Serial Number

The product's serial number, if available. The format will look something like this: AB0123-CD456789. After we receive your reply, a Customer Service agent will. Oct 21, 2010  How do JBL serial numbers work and were they continued from one incarnation of the company to another. I have a pair of 150-4Cs with serial numbers 12832 and 12837.

Hi Scott, It is kind of rare to find factory installed JBL 120F's in a twin but not unheard of. Supposedly, if they are original to that amp, they would have an ink stamp on them that matches the stamp on the tube chart inside the cabinet.or a stamp that would be a code like AA2565.25th week of 1965. Unfortunately these stamps are not always on the speakers and are sometimes on the cabinet, or on the inside or outside of the chassis. Another clue on a later 60's speaker might be a tiny F punched into the foil label. In the end, only your ears matter. JBL's are universally considered 'hi-fi'.very clean, good bass but perhaps a bit harsh on the treble side.brittle maybe? I had a factory JBL equipped twin for a very short time.

It was a late 68 production with gray framed JBL D120F's in it and the factory JBL badge on the grille cloth. Absolutely mint. I sold it because, for me, it did not sound good. It was a kind of sterile amp.

For some sounds it was a perfect, like stepping back through time to a Memphis recording studio. Clean, clean clean. Good with a tele for country. If you prefer your sound a bit dirtier, or perhaps, looser, the premium price of a JBL equipped black twin might not be worth it. Thank you – great response and much appreciated!

This Twin does not have a stamp on the tube chart that would match the pattern you listed. There are two stamps on the tube chart: Production “58” and “PG” stamped near the bottom right. Unfortunately I only have pics of the amp to go on for a few more days. The pics I have are, however, very high resolution and cover almost all of the speakers + cab in the back. The speakers and do NOT show an “F” imprinted on the foil label of the speakers. I have the serial numbers on the speakers and, from what I’ve been able to gather, they look to be from around the same time as the amp (1965).

(Our EU colleagues believe that even age plus service provisions should be considered indirect discrimination, but there may be a better argument that such a provision is justified, due to the fact that it is not just intended to reward older employees but also company loyalty.) In my experience, many companies are assuming the age discrimination risk and keeping the retirement provisions for EU employees.

Unfortunately the pics do not really include the cone (so I can’t see any stamp on the cone). The frames are gray with yellow JBL on the driver.

Serials are 117xx and 120xx (where “xx” is a number). They say “signature speaker” across the top (but not “Jim Lansing signature speaker” like the ‘61s apparently). And I’m with you on the “ears” bit – I won’t hesitate swapping these out if they aren’t what I want.

I’ll just carefully pack them up and, if I ever sell it, they’ll go with it and make it a premium cost J I have a pair of Tone Tubbies in my 73 Twin that are amazing – maybe they’ll be great in a ’65 too. I hope to find out!

I appreciate your time on this, Kevin – thank you for any insights! Slim shady lp cover. Scott kevin 13/1/2010, 20:28 น. It is highly likely the chassis was made in '65 and the amp assembled in '66.however, with it being JULY of '66, this scenario becomes a bit less likely. Ask the seller if there is a PG inkstamped somewhere inside or outside the chassis.Ask the seller for all the #'s off the transformers.IE: they should all be 606-6xx.or 606-6-xx.the X's represent the week of the year. They should all be starting with that 6 for 1966 after the 606 which stands for Schumacher. Also, does it say Fender Electric Instruments or Fender musical Instruments under the Twin Reverb Amp logo.post 1966 it would say 'Musical' not 'Electric'. I ended up not buying it.
