Dating fender concert amp fetching and updating cursors
Will withstand high temperatures of pre-amp tubes, reusable when you change tubes. Contains two 8-pin sockets, two "bear trap" retainers, four mounting screws, two 470 ohm screen grid resistors (Metal-Film Flameproof for safety), and two carbon composition 1500 ohm control grid resistors. 1.19" in diameter, 0.86" tall (not including pins and center post). One year warranty, triple-diode construction for reliability and long service. Do not install in an amplifier that does not have a standby switch - always use the standby switch in amps so equipped when using the 5RTR. 90 capacitors total, each individually bagged by type and value.
An economical alternative to more expensive tube dampers. Fender Vintage Amp (60s Blackface and 70s Silverface) Power Tube Socket replacement kit. ) from the original blackface and silverface eras which have two power tubes (6L6 or 6V6). Because there is no warm up of a rectifier tube when using this solid state device, it is absolutely necessary that a standby switch is used in conjunction with this device. Do not install in an amplifier that does not have a standby switch - always use the standby switch in amps so equipped when using the 5SSR. Contains 5 each of the following values in 630V Axial Metal Film (similar to Mallory 150 style): .001u F, .0022u F, .0047u F, .01u F, .022u F, .047u F, .1u F, .22u F, .47u F and 5 each of the following values in 630V polypropylene radial (similar to orange drop style): .001u F, .0022u F, .0047u F, .01u F, .022u F, .047u F, .1u F, .22u F, .47u F.
We combined all of our information into a computerized database for this project and for the past 18 months have been slowly (sadly, very slowly) gathering information that we collect ourselves as well as from other people. What we need is the following: 1) Model name 2) Model number on the tube chart 3) Date code letters on the tube chart 4) Speaker codes (if speaker is original) 5) Transformer codes (if the amp doesn't have date codes on the tube chart) 6) Cosmetic features (flat/raised logo, tweed/tolex, blackface/silverface, rough/ smooth blond tolex, white/skirted knobs, TV-front/wide-panel, etc.) One very interesting and very important factoid has surfaced regarding the date code letters on the tube chart.
In the fall of 1965, Fender switched from stamping these numbers in black ink, to dark green ink.
TUBE SHIELD, BAYONET "PUSH AND TWIST" TYPE, ALUMINUM, 1 15/16" TALL, SET OF 6. TUBE RETAINER WITH GRIP TEETH, DESIGNED FOR OCTAL TUBES WITH PHENOLIC BASE SUCH AS 6L6 OR EL34. Perfect for Vibrolux Reverb, Vibroverb, Super Reverb, Deluxe Reverb, Pro Reverb, Bassman, Bandmaster Reverb, Tremolux, etc. The kits are assembled from premium capacitors made by F&T of Germany (filter capacitors) and Illinois Capacitor (cathode bypass capacitors).
When hot, the filament releases electrons into the vacuum: a process called thermionic emission.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 electrodes are attached to leads which pass through the envelope via an air tight seal.On most tubes, the leads are designed to plug into a tube socket for easy replacement.
Besides, no article in the Dating Fender Amps by Serial Number series would be complete without some interesting information, n’est ce pas?
