Your amp runs cooler! When used in guitar or hi-fi valve amplifiers this diode will provide a robust and long lasting low power consumption alternative to Valve rectifiers and can be soldered directly across the appropriate pins on the valve rectifier socket (two diodes required to replace a typical double diode valve rectifier, four required for a full bridge rectifier with transformers with secondaries with no grounded centre tap). Use of solid state diodes will reduce the load on your power transfomer by as much as 20 Watts compared with a heater current thirsty and inefficient valve rectifier! It may also be advantageous to solder a suitably rated 0.01uF capacitor across each diode as the very fast switching of solid state diodes can otherwise cause spikes on the B+ HT rail. A 10A diode may seem like overkill when you consider that even large valve amps only draw around 150mA on their HT rails, but these big chunky components look "vintage" and don't look out of place in your amp chassis.... and have got to be one of the cheapest upgrades for improved power and reliability you can fit to an amplifier. More Power out! Note that if you do replace a valve rectifier with solid state diodes you will probably end up with between 10V and about 40V more on your HT supply compared with before... which should give more output power and headroom but may require rebiasing your output valves. Do give some thought to other component voltage ratings... 400V capacitors can be easily changed for 630V capacitors for peace of mind! Sag Resistor for Guitar Amps If you want to change to diodes and improve reliability without losing the characteristic soft sound a valve rectifier contributes towards a guitar amp when you overdrive it, you can fit a high power wirewound resistor (from 100 Ohms to 330 Ohms at 20W) in series with the diode rectifier output before the first main smoothing capacitor, at the expense of burning some of that saved power as heat instead of sound!
