Common Noise Fix - Plate Resistors

Preamp Plate Resistors

Is your amp getting noisy?  In vintage Fenders, the 100K plate & slope resistors in the preamp tend to get noisy over time (hiss, snap, crackle, pop)!!  That intermittent staticy/crackly sound is often caused by one of three things:

1) Weak or noisy preamp tubes

2) Dirty or loose tube sockets

3) Noisy plate resistors

These 100K plate resistors regulate the high voltage feeding the plates of your preamp tubes.  They often become noisy as the decades roll by (often described as the 'frying eggs' sound).  Replacing these resistors is a big help in reducing the noise floor of your Vintage Fender Amplifier.

YES, resistor TYPE has an impact on sound!  Since carbon comp resistors have been marked as obsolete by the major manufacturers and production has largely ceased, we have recently switched to a very high quality and excellent sounding carbon film resistor.  A good carbon film sounds spectacular (vintage Vox and Marshall amps used carbon film resistors for example), and the resistors we use are not carried by your typical 'amp parts' suppliers.  Gotta dig a bit deeper to find these!!
