10. e reverb recovery circuit R13 provides a ground reference or bias for the input of V3A This prevents instability in V3A if the reverb recovery cable is disconnected from the reverb pan V3A senses the reverb return signal and amplifies it with a gain of about 37 The Tone control R17 attenuates the high frequencies above 3kHz through C9 C10 provides a slight bass roll off which is affected by the position of the Mix control in relation to the input impedance of the guitar amplifier V3B is a cathode follower unity gain buffer amplifier for the dry signal C11 is a non polarized metalized polyester film capacitor which is located across the high voltage transformer secondary suppresses EMI frequencies from 20kHz to 30mHz This is necessary to conform to modern day NEMKO safety requirements The pot mounting brackets are all connected together via traces on the circuit board The trace connects to the star audio ground through R22 R22 places 15 ohms of resistance between audio ground and the pot mounting brackets This is done for two reasons Fist with the circuit board installed the pot brackets are physically connected to chassis earth ground R22 isolates audio ground from earth ground through the pot brackets This eliminates internal ground loops Secondly when the circuit board is removed for repair and testing R22 provides a ground reference 15 ohms for the pot brackets R23 places 15 ohms of resistance between audio ground and c
