dating my Bass Mate

Postby Eye Banez on Wed Jan 21, 2009 8:58 pm

I may have asked this some time ago, but my Bass Mate has a serial number starting with a "B"6790. Does anyone know if the "B" simply names it a Bass Mate and perhaps the 6790 indicates it was built in 1967?

It's a 6V6 model, volume, tone and a solid state rectifier.

I have no knowledge of serial number dating for Traynors. I usually just date the components by the codes. Have you noted the codes from the speaker, transformers and pots?

The only thing I can see for sure without taking it apart again is a smaller transformer from Hammond Canada with the number 79466.

The Velvet Black site describes how to date them, but the only reference I can find with a letter in front is is the early 60's and they are only supposed to be 3 digits...ie; M601for a YBA1A Bass Master Mark 2.

I tried to post a picture but it says the files too big.

Thanks

...and there was me thinking you'd pulled a bass player and needed advice on what to wear tonight. :roll:

...my bass player is far to weird to date.

I believe I may have answered my question about the year more or less. I down loaded a schematic for a 6V6 driven Bass Mate which were among the earliest versions, and it shows the transformers 79465 and 79466. The schematic is dated Feb. 27, 1967.

According to Velvet Black, the 6V6 models are pretty rare to find in good shape. Mine sadly has no original logo or grill cloth, so I had to ad-lib. It does sound awesome though.

by 1970 the first digit of all serial numbers on all Traynors was the year so 67 is a good guess

Since the amps were designed to be part of store rental stock they moved to first digit is the year
serial number dating system very early. They used this encoded date to help manage rental stock with the idea that after two years of rentals the items should be sold off as used. This was actually part of the Grassroots Traynor marketing plan.

Traynor dealers were encouraged to start rental departments with the stuff, dealers who followed the "system" did very well.

Thanks for the info. Hammond Canada mailed me back and said that those particular trannies were indeed manufactured in the late 60's.

My next project is trying to find out more about my Garnet Stencil "Mann" M100TR. It's a 40w head and 2 x 12 Cabinet. The only schematic I can find lists some tubes that are not in the head that I have. (6JW8's) I mailed Eurotubes and they put me onto Audiotubes.com. So I wonder if it's not the right schematic for the unit. It actually comes up as a M100TAR.

The search continues...perhaps a new thread?

I suppose you have looked at Schematic Heaven. What they have there as a M100TR carries 6L6GC's.

6jw8 on the tube data sheet doesn't seem like the best option for a guitar amp tube....TV oscillator and frequency control tube.
WHat do I know, though?

Are the sockets original, and have you measured the voltages?

Thanks Dean,

That's the schematic I found as well. I'm very sure the first time I did a tube change they were all 12AX7's except for the 6L6's of course. I'm not a tube tech so I'll see if I can find someone to help me out. I'll post what I find out.

Hello eye banez. I have the same amp with serial number B6728. I was wondering if you found anything else about the date. I was unable to find anything on mine other than the serial number. The pots read a strange 1 meg s 9591 dj j6, which I was unable to find anything about. So our amps are only 50 numbers apart or so. Mine also has the solid state rectifier, and sounds fantastic. I would like to try a big ben , but a weber is in there now and sounds dam good. Thanks[100_2535][100_2526]

As you can see, it's been a long time since I posted on this forum. Since 2009 I have sold all my vintage amps for new hand built Luker Amps.

I think it was left that the amp was indeed a '67. I believe the earlier ones came with a tube rectifier (65, 66) and then a solid state rectifier.

It was a great amp. I put a Eminence 15" and used JJ tubes which made it come alive. Wish I still had it, but my first Luker (Tiger 20 model) was basically the same circuit, 2 - 6V6 power and a 12AX7, 12AU7, but has a solid state switchable to JJ GZ54 tube rectifier system. Put an Eminence Red Fang 12" into it. I needed something with more stuff for club gigs.

Enjoy your amp

Thanks man. I don't know how long I will be keeping these amps either, but for the last year I can't stop loving them all. Bob
