So why Use a 5U4GB rectifier pair?

Well, the first thing to realise is that the rectifier valve is NOT in the signal chain. It’s there simply to change AC to DC, a process known as rectification.

The reason rectifier valves are still used is interesting. They are actually not that great at doing the job they are intended to do! That is, change AC to DC.

If the amplifier is loaded, by say a heavy power chord from your trusty Les Paul, the DC will ‘sag’.

This is because the rectifier simply can’t keep up. In contrast, a diode rectifier will barely sag. (sagging means the DC voltage drops before recovering.) But here’s the thing. Guitarists have come to like this effect, hence the continued demand for valve rectification.

And of course, back in the day, there were no decent solid-state rectifiers. So the 5U4GB and similar types were the only game in town.

There are still hundreds of thousands of vintage amplifiers out there which use rectifier tubes.

So now you know!
