Dating a fender twin reverb amp
1Looks to be a victim of long-term salt-air exposure (residence in Florida or other Gulf states? The corrosion might be a cosmetic issue only and not a factor that would affect the proper operation but it should be explored and examined prior to purchase.
Arjay_________________"Here's why reliability is job one: A great sounding amp that breaks down goes from being a favorite piece of gear to a useless piece of crap in less time than it takes to read this sentence." -- BRUCE ZINKYRecently I have come across a silverface Twin Reverb at the local music store and I'm not entirely sure what year the amplifier is. I haven't been able to read the tube chart on the inside of the amplifier, it seems someone had tried to tear it off at some point.
The type of face, grille cloth, type and number of speakers, type and number of knobs, etc.
only come into play when you’re trying to value the amplifier in the Blue Book for Guitar Amplifiers per the model description that is provided.
The transformer code is EIA606-102 (right over it were the numbers 013691). The serial number is F106486, but right under it is the number 1860 stamped in what looks like black ink.
If I'm going by Fender's support page correctly, would this amplifier be a 1961 model? If I'm going by that chart right, then this amplifier would have been manufactured in the year 1970?
The Tube Chart is the most accurate as to when you amp left the factory.
However, your transformer was made in the 50th week of 2007.HTHArjay_________________"Here's why reliability is job one: A great sounding amp that breaks down goes from being a favorite piece of gear to a useless piece of crap in less time than it takes to read this sentence." -- BRUCE ZINKYLooks like the amp is in serious need of a new master-volume knob. Try wheeling and dealing with the seller before you buy -- anything beyond 0 for this one is a bit *optimistic*, methinks.Arjay_________________"Here's why reliability is job one: A great sounding amp that breaks down goes from being a favorite piece of gear to a useless piece of crap in less time than it takes to read this sentence." -- BRUCE ZINKYI don't know Arjay's feeling on this,but there seems to be quite a bit of rust on the transformer that can be seen in the picture, I've never liked to see that and know that rust can never be a good thing,you might want to look at some of the exposed parts of the underside of that chassis and see if there's corrosion elsewhere.Other things to look for include chasses placed in cabinets from a different year, “doctored” tube charts, non-original control plates (usually reproductions) on silverface amps, original transformer bell ends (they have correct date codes, of course) on non-original transformers, and non-original knobs (either repro or silverface knobs on blackface amps).unusual things can be found such as the empty “Pulse Adjust” hole on the rear of early ’60 brown amps, the “middle” volume control, use of tweed style grill cloth, strange non-documented transitional circuits, and changes in tolex color including the super-rare cream colored “brown” tolex that is found on some late ’60 amps. Given that people may refer to this information seeking specific production quantities of amps they are curious about, it should be pointed out that the serial numbers apply to chassis types, and not specifically to amplifier models.
Looking at serial numbers next to the ’60 5G5 brown Pro Amp for example, we see numbers ranging from 00001 to 02000, suggesting that there are 2000 of these amplifiers made in ’60.
The research I've done gives a different date for each of the items above and I'm not sure if it's a reissue because of the date on the board or if the original board was replaced with a newer one the transformer says it's a "1967" is it a Frankenstein?
