Unfortunately there is a lot of fake vintage gear floating around on the used market. Most of which can be traced back to one notorious dealer in UK.
In this blog post I will be going over a few basic pointers for identifying fake vintage Celestion speakers. Hopefully this will prevent a few people from getting stung.
Why Bother Faking Vintage Celestion Speakers?
You are unlikely to see fake pre-rolas for sale on their own. It is far more lucrative for dealers to make or ‘lash-up’ an entire vintage Marshall speaker cabinet or combo amplifier. The speakers are just a small part of that, and would be doctored to suit the gear being faked.
For example, a non-valuable speaker model – lets say a T1614 from 1972, might be turned into a T1221 from 1966, then fitted into a fake 1966 Marshall bluesbreaker amp.
Spotting fake speakers inside vintage Marshall gear is an important warning sign to avoid buying that particular amp or speaker cabinet, and tells us quite a lot about the seller too. They are either clueless about the gear they are selling, or dis-honest (in my experience most dealers will plead ignorant when you query this stuff). Either way, its a good idea to blacklist the seller and take your business elsewhere!
The main hotspot for fake Marshall gear is the pinstripe period: mid 1965 to early 1968, and therefore this is the period of Celestion speakers we need to be most vigilant about.
The rest of this blog post will focus on the small details we can use to identify fake speakers. Fairly tedious and nerdy sorry (leave now if this freaks you out) but is the only way I can do it.
Fake Ink Stamps
All genuine vintage Celestion speakers made betwen 1952 and March 1968 had their date codes printed on the front gasket of the speaker. Fake date codes will usually be printed on the chassis leg instead.
So any vintage Celestion greenback speakers with date codes earlier than March 68 stamped on the chassis leg are likely to be fake.
Chassis Leg Stamps
From April 1968 onwards, Celestion date codes were stamped on the metal chassis instead. However, any fake date stamps printed on the chassis are still very easy to differentiate, based on the following characteristics:
- Horizontal Print vs Vertical Print – Celestion stamped their date codes horizontally on the frame from April 68 to Dec 68, then vertically from the beginning of 1969 onwards. Fake stamps are usually printed vertically.
- Black Ink vs Grey Ink – Celestion only started using black ink on the frames from about mid 69 onwards, before this it was a pale grey. Fake date codes are usually in black ink.
- Circular stamp – The circular quality control stamp will always be present on a genuine speaker. It will be missing on about 90% of fake speakers.
From the beginning of 1969 to late 1976 Celestion included an additional ‘inspection letter’ with the date code. For example you might find the date code ‘GB17 Y’ with the ‘Y’ being the inspection letter.
Some fake vintage Celestion date codes include the inspection letter way too early, such as with a 1967 or 1968 date code. Somebody recently showed me a 1968 date code with the model code ‘T1281 Z’ next to it. Pretty wierd looking, and I would love to add the photo here but the owner would not give me his consent to use it.
Wrong Chassis & Solder Terminals
Celestion used two main types of chassis; the ‘one tab’ and the ‘four tab’.
The earliest I have seen the four tab chassis is May 69 (EB date code) on the Vox silver alnico. On greenback speakers I have not seen it any earlier than July 69 (GB date code). It has a ‘tab’ on all four sides, and a small cutout at the sides of the solder terminal:
The earlier one tab chassis does not have the extra tabs or the solder terminal cutouts:
Watch out for fake vintage Celestion speakers that have the four tab chassis, but with a pre-69 date code:
The ‘Marshall T1217’
Watch out for the T1217 model speaker with a white Marshall label on the back. Marshall have never used the T1217 to my knowledge.
The fake white labels are fairly difficult to differentiate from the genuine ones, but usually the fake ones show very little signs of ageing. The genuine ones can sometimes go a bit yellow and transparent over the years.
Fake and Repro Labels
Notice the impedance shown on the labels:
The 15 Ohm pre-rola labels were standard from 1966 onwards and were phased out from Aug 1968 onwards. These are the 20 watt G12M and 25w G12H labels:
The 16 Ohm pre-rola labels first appear in Aug 1968 and were phased out from April 1971 onwards. These are the 25w G12M and 30w G12H labels:
Fake labels will often have the wrong impedance on them:
The heritage series labels are easy to identify by their glossy finish. There are also some very obvious repro labels around with a wierd looking sloping font. Notice both of these label types also have the “incorrect” 15 Ohm impedance:
Fake Cone Stamps
Watch out for any peculiar looking cone stamps. Often accompanied by a white smudge – probably an attempt at removing the original cone stamp.
Dont Get Stung
So, hopefully you have picked up a few pointers here. The main thing to look at is the date stamp and the type of chassis – they really stick out like a sore thumb once you know what to look for.
When buying vintage Celestion speakers, and especially vintage Marshall gear, always make sure you do your homework on the item, but more importantly – always research the guy selling it! Stick to the reputable dealers.
