Looking for some data on the Telefunken RGN2504 rectifier and its equivalents:
Valvo G2504
Philips 1815
Klangfilm KL76303
The datasheets available for these tubes do not quote the Isurge / Ipeak values.
Philips 1815: https://frank.pocnet.net/sheets/170/1/1815.pdf
Table of specs for various 4V rectifiers: https://frank.pocnet.net/short/054/0/027.pdf
The only information I have been able to find is a Spice model on Duncan Amps added by "The Engineer" which rates the RGN2504 at 1.5A surge and 530mA peak, but I have no way of verifying if those values are accurate.
Has anyone come across this information? Much appreciated.

Can't help it, I'm going to ask:
Why would anyone want to take these venerable old valves and Subject them to anything even remotely close to their design limits?
Why are you asking, if performance matters you'd be looking somewhere else completely?

I've rarely seen any rectifier tube datasheet that shows peak current limits. Instead, a maximum filter capacitance and a minimum transformer DC resistance is given for C input filters.
The only diodes I know of given Ipeak values are booster/ballast diodes from TV service.
Best regards!

there are more: EZ80, EZ90, 6X4, 6Ц4П, 6X5 ...
Really? I have come across it often in rectifier datasheets, at least the peak steady-state current. But I think you are right Kay, for these very old rectifiers a minimum transformer DC resistance and maximum input capacitance are more common to see.
Oh well, I guess I will continue to wonder. Thank you for being helpful 🙂

Ok, thank you! I've missed that - most probably 'cause I don't care too much in tube rectification at all. There are far more better options 😉.there are more: EZ80, EZ90, 6X4, 6Ц4П, 6X5 ...
