Members ChrisFFTA Posted September 20, 2011 Members Share Posted September 20, 2011 Could a 72 (by its s/n) silverface have transformer code dating 1970/71? I know with guitars that pots, neckplates and neck stamps often were out of wack... same for the amps? Link to comment Share on other sites More sharing options...
Members hangwire Posted September 20, 2011 Author Members Share Posted September 20, 2011 Probably I think of fender as kind of an assembly line builder- with bins of parts that were picked and restocked as needed Link to comment Share on other sites More sharing options...
Members hangwire Posted September 20, 2011 Author Members Share Posted September 20, 2011 I think i discovered an issue - when playing certain notes you can hear a rattle. I kept thinking it was a guitar behind me that was just resonating, but I think it is the amp... is that a ghost note [never heard one and no video examples on one besides a harmonica demo] or just some needed screw tightening that is causing a rattle?

Members goodhonk Posted September 20, 2011 Members Share Posted September 20, 2011 could be tube rattle, baffle rattle, screw rattle, bad tube... Link to comment Share on other sites More sharing options...
Members hangwire Posted September 20, 2011 Author Members Share Posted September 20, 2011 could be tube rattle, baffle rattle, screw rattle, bad tube... I assumed I would have my amp guy take a look at it eventually... so no big deal i suppose. you can't really hear it unless it is the last note you play and hold it... if just playing it kinda stays in the background Link to comment Share on other sites More sharing options...
Members goodhonk Posted September 20, 2011 Members Share Posted September 20, 2011 i had a tube that would rattle like a puerto rican space shuttle when i would play an A. Link to comment Share on other sites More sharing options...

Members hangwire Posted September 21, 2011 Author Members Share Posted September 21, 2011 maybe it is something in the room rattling actually, as my other amp just did it to when comparing the reverbs also, the tremolo has a background "ticking" that you can hear when you stop playing... leaky cap'd?

Members goodhonk Posted September 21, 2011 Members Share Posted September 21, 2011 ^ my twin does that, my drri did too; i think it's normal. i've got a tool case that i use for my cables and junk, it rattles so much that i have to take it out of the room.

Members hangwire Posted September 21, 2011 Author Members Share Posted September 21, 2011 Yeah but the amp I did have before never had this issue Maybe something got weirdly shifted when I brought the amp in.... I'll have to take it downstairs and see later. Link to comment Share on other sites More sharing options...
Members imbuedblue Posted September 22, 2011 Members Share Posted September 22, 2011 That ticking could be a leaky cap, but it could also be lead dress. The lead dress got all rat's nest during the Silverface era. Anyway, you can try moving the wires on V5 to see if that silences the ticking.

Members GreaserMatt Posted September 22, 2011 Members Share Posted September 22, 2011 it's in nice shape, you scored bigtime +1 I'd love to buy one of those at $425... Link to comment Share on other sites More sharing options...
Members hangwire Posted September 27, 2011 Author Members Share Posted September 27, 2011 a little cleaning and tightening and it is all good thinking of selling though because of crazy prices, and my flotAtone is really my sound... it would be nice if the Flot had more than 1 tone control... aside from just throwing an EQ pedal in the back of the combo, can tube amps be modded to turn a tone control into a 3 band eq???

Members imbuedblue Posted September 27, 2011 Members Share Posted September 27, 2011 The tone stacks in tube amps are usually passive, so yes, you can replace the single tone control with a bass-middle-treble arrangement. The things you need to be concerned about are real estate and dealing with extra insertion loss. Basically, whenever your signal goes through a tonestack some signal is lost. The classic three-knob tonestack will obviously have more insertion loss than a one-knob tone control. Usually, there is a stage following the tonestack to help make up for this insertion loss. The most elegant solution--one that wouldn't involve drilling new holes in the chassis for mounting extra pots--would probably be to go with a two-knob tonestack using a single dual-concentric potentiometer for bass and treble controls (i.e., the Baxandall tonestack). http://amps.zugster.net/articles/tone-stackshttp://www.duncanamps.com/tsc/index.html Link to comment Share on other sites More sharing options...
