6336 as a Rectifier

poynton · 27th February 2008, 10:10 AM

I have a few 6336s.

Could I use one as a rectifier by strapping the grids to the anodes and commoning the cathodes ?

If so, what would limit the current? The grid ?
What current could I expect to pass ?

Not ideal situation....

But if you do try it, Tie G1 to the cathode or it will self destruct by excess current/volts through G1!

connecting G1 to cathode will make it electrically 'invisible' to the valve....

Has the 6336 got separate cathodes per section...?--Not familiar with it....

As to current, volts drop etc, who knows!

BTW, where in Wales are you...?

I'm in Swansea....

You can make a mediocre rectifier that way, yes. It will take 30 watts of heater power, timer circuitry to prevent application of power until the heaters are completely warm, and will give you a max output current of 300mA or so per section. The drop will be higher than a GZ34; at 100mA, the drop will be about double. The max voltage will be considerably lower.

Seems a waste of a perfectly good regulator tube. A cheap GZ34 will do a much better job.

OK, thanks guys.

I will not bother then.

Or you can try these:

The sockets are a bit hard to find, but they're easy enough to make.

The load ! As with any rectifier

Wasn't WE who used a 845 as a rectifier for another 845 ?

pls dont try 6336 as rectifier,,,,6336 is a nice tube for output stage ..SE ..PP ,,or parafeed

I second that. The 6336A works great in SE output stages. Just think of it as three 6AS7's in parallel. I have one running in a cathode follower output stage that sounds great. Power is about 10 WPC with distortion at 0.5%.

Hello Tubelab,

Just curious: could you post or pm the schematic of your 6336A -SE? Could not find it on your site.

Best, Arjen.

My 6336 SE Parafeed ampl ...15W/ch,, 20H load choke, 2mf coupling cap, with marvellous sound
