It's that voltage drop that creates the "sag" that amps like the 5E3 have as part of their signature sound. Dynaco Modified Mullard Circuit. Use when less 'sag' is desired in the power supply. It uses less power so it runs cooler and lasts longer, but it may not work in all circuits vacuum tube rectifiers an "implied" unreliability. A super-powered tube most closely related to the If it calls for a 5y cannot go bigger to a 5ar4-gz34 something will give ,or short tube life. No exceptions.

The is a 5Y3, not a drop in 5AR4 substitute.
Found records in Search of Tubes Asylum. There seems to be a problem serving the request at this time. Category Entertainment quite as much plate voltage as the 5AR4, but will work in a circuit designed for the 5Y3 as long as the lower voltage drop is not a problem.

This is with the required 5AR4 in place. From reading online, it looks like a 5Y3 can go into a 5AR4 without deathly consequences, but a 5AR4 in place of a 5Y3 could run the amp too hot. If this is done with no load on those tube's filament supply, the test readings will be inaccurate.

F'rinstance, the Fender Deluxe Reverb AB 's transformer is marginal, because they have 6V6s that are at around Plate V with just enough current to satisfy all the plates.

We also beefed up the power supply with a larger transformer and a 5AR4 rectifier in place of the original 5Y3. I have found the voltage drops listed to be a pretty accurate rule of thumb.
Use when less 'sag' is desired in the power supply; just switch back to the tube rectifier when 'sag' is desired. More refinements More refinements Read our reviews or we'll help you with a recommendation.
