James,

I'm sure it would be a tragedy for anyone to miss the "sripping housewives" Do they now have mpeg artifacts? what's their bitrate?

Cheers,

Still too busy at work No stripping housewives either

Thanks for all the input. John's application was the origional inspiration for my thoughts but I have a pair of 845's myself so one day I will need this too.

The STV280 regulator is a nice design that yields four stabilised voltages out at 280V, 210V, 140V and 70V from one tube - four anodes - useful for some apps. and it's still relatively cheap at about 18 euro.

When I get time I'll rework redraw the design incorporating your suggestions to produce a design that might actually work!

ciao

James

Hi,

Whilst I realise that this thread is not solely for my benefit, some posts have been aimed at a solution for my HV problems.
So thanks to all for their input on this thread.
I have given shunt regulators some consideration, but have decided to re-invesigate high voltage series regulators.

I may open an HV Valve Series req thread shortly.



Cheers,

Default VR280 ANYONE?

Hi,

I thought you all deserve a piccie of the STV280.
Two versions exist,one at 40mA and the bigger brother is good for 80mA.

This is the bigger one:

Cheers,

Default EL509

Hi,

I'll agree that an EL519 would work fine.
If you want to stick with octal types the KT90 would do the job too and you get rid of that anode cap too.

For the curious:
