Dating fender vt bassman cabinet
Produced from 1954 until 1960, these models are called the "narrow panel" tweed amps .
Fender introduced the model 5D6 "DK" in November 1954 followed by the 5E6 Bassman Amp during early 1955.
The P10Q Jensen speakers are more able to manage stronger electrical input power and generate better "clean" output sounds than previous installed P10R Jensen speakers.
The P10R Jensen speakers were shipped within all Fender Bassmen from late 1954 until early 1960.
The 5D6 was a major departure from the earlier 5B6 Fender Bassman model.
Designed by Freddie Tavares, longtime R&D man at Fender, Instead of the single 15" speaker, four 10" Jensen Alnico P10R speakers were used.
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.
During 1958, Fender introduced the model 5F6-A Bassman model.with a front panel that had a rectangular grill cloth with rounded corners and looked much like a television of that era.In 1953 the cabinet designs were changed to the so-called "Wide Panel" design, with a 5 inch wide tweed covered panel above and below a wider swath of grill cloth.Since several models can share one chassis type (for example, the early brown 5G7 Bandmaster, 5G5 Pro and 5G12 Concert), this kind of interpretation is inaccurate.Instead, there were approximately 2000 of these chasses produced, which then ended up as one of the three models in question.
