Given that NOS TF caps seem to be increasingly hard to come by, is there a modern equivalent type that can satisfactorily replace them with a similar footprint & pinout? I'm specifically interested in the 250V rated types found in old 'scope smps.
No , the main feature is that they are brightly coloured to keep guitarist tweekers happy, as the visible colouration carries through to the tonal colouration.
Also when the electrolyte leaks out, there is a much sweeter fishy smell than the usual rank temperate latitudes fishy smell of the cheap types of caps
Mpfffff.... Within very basic parameters and manufacturing standards, a cap is a cap is a cap.
Apart from the mystery, smoke, mirrors and hokum surrounding "bumble-bee/tr opical fish" caps and so forth, about any modern polyester film cap of dece nt manufacture is its *actually functional* equivalent.
Keeping in mind that the fuzz-box crowd is really looking for an R/C networ k rather than a cap, despite the schematic, why these too-often leaky caps are sought after becomes easier to explain. I have a neighbor down the bloc k for whom I save my pulls and leakers of this nature. I try to tell him th at all he really wants is a 1 or 2 meg resistor parallel to an 0.047 cap - but he wants it all in one package complete with a bakelite case.
