Carlsbro

Since 1959, Carlsbro Electronics Limited, Nottingham, England

...all our equipment was issued with a serial number which was stamped into the metal of the early valve amps and then a self-adhesive number was applied to the back of all subsequent units. ( from about 1974 the transistorised units also had a separate F/P number inside the front panel to identify the model ).

There is no "date code system" to the serial numbers except for the period 1988 to 2000 where the first two digits were the year of manufacture ( to within about 6 months ).
All the serial numbers going back to 1973 are held in an old archive of manually written books which are too numerous to archive into an electronic file, so any enquiries about dates etc need a search through them which can be somewhat laborious as you can imagine.

I wish you luck with your project and if you find yourself with a couple of free years on your hands, you can catalogue our archive! LOL [Source: Peter Longley, Technical Advisor, Carlsbro Electronics Limited, email 12/2/2007]

Carol-Ann Amplification

Alan Phillips is the owner of Carol-Ann Custom Amplifiers, LLC. a full service custom boutique tube amplifier builder located in North Andover, MA, on Boston's North Shore.

"The business was formed in to a fulltime LLC in 2006, though there are many amps out there that I've built since 1985, only amps built after 2002 bearing the Carol-Ann name. In the early days I built a few solid state PA power
amps as well as solid state and tube guitar amps. Most of the early guitar amps were Marshall derivatives.

Dating Carol-Ann amps

Serial Numbers take a 6 digit form xxyyzz, where xx is the year, yy is the month, zz is the production number for that month.

Limited edition amps may have a different numbering scheme that makes it often impossible to tell the production date.
Some amps may not have had a serial number written on them simply because that step was omitted during a very busy production run. If any owners contact you with this scenerio, I can provide the correct number for their amp.

The serial number is either engraved or written on in black, red, silver or gold, It is always located on the back panel.

Recently I've started writing the number inside the chassis in gold pen too.

A couple of amps have cryptic messages inside them. This was  the case when I knew a customer who was buying the amp was closely associated with another Company and the amp would very likely be reverse engineered. I don't bother about this any more. It is what it is and I've chilled out about it.

Contrary to common rumour, I don't goop production amps at all. With the exception of one amp that was fully gooped with Military spec encapsulating compound, I use a material that is an industrial black hot glue to protect the circuit from physical abuse and to help shield sensitive areas from induced environmental noises such as stage lights. This material can be easily removed for servicing with the use of an industrial hot air gun to soften it. I guess it does prevent the passive onlooker from reverse engineering or from taking meaningful photos of the circuits, but if someone wants to know what's going on, removing the material is real easy.

The name came from my sweet Italian wife Carol-Ann. I built an amp for myself in 2002 when I just moved to the States, right after we got married. To be honest, we couldn't really afford it at the time and the way I got around Carol was by naming the amp after her. I figured it would make it more difficult for her to be mad at me."

Carr Amps

" We started Fall 1998. All amps have a serial number on the chassis and there is a tube chart stuck to the inside wall of the cab that has the serial number too. Most of the amps are dated on the tube chard and all are dated inside the chassis." [Source: Steve Carr, email 21/3/2008]

Cleartone Musical Instruments

(CMI)

Note there are 2 CMIs.

In 1966 Jim Marshall made a huge mistake and signed a 15 year arrangement with international distributor Rose-Morris.  Rose-Morris marked up international sales 55% vs market rate at time of around 15%.  This limited the potential market for the amps, hence not many were sold overseas.  Under the terms of the deal Jim was unable to market the Marshall name directly. In order to keep turn over up Jim established other brands and distribution arrangements for Marshall made products under other names eg. Park.  Jim founded a wholesale business Cleartone Musical Instruments which sold Slingerland, drums and other lines.  He made the Park line for his friend John Jones and distributed them under Cleartone Musical Instruments or CMI.  From 1976-1977 PA gear and a small number of guitar amps were made under the CMI brand.  [Source: Jim Marshall, Father of Loud,  By Rich Maloof ]
