Description
Are you looking to replace your EZ80 rectifier valve? Look no further!
Rectifier valves, like the Tesla EZ80, are used in a large number of vintage and reissue guitar amplifiers.
We sell a superb example of the EZ80 rectifier made by Tesla.
This version has a thick glass envelope and extremely robust electrodes. This makes it the perfect workhorse for those guitar amplifiers which use tube rectification.
It’s become quite chic to add a rectifier tube to a new guitar amplifier design. Guitarists just love that ‘retro’ feel!
So why use a rectifier valve like the Tesla EZ80?
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 demand for valve rectification.
And of course, back in the day, there were no decent solid-state rectifiers. So the Tesla EZ80 and similar types were the only game in town. There are still hundreds of thousands of vintage amplifiers out there which use rectifier tubes and more are still coming into the marketplace.
So now you know!
