Telefunken RGN2504 Isurge / Ipeak Specs?

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The datasheets available for these tubes do not quote the Isurge / Ipeak values.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.

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 :)
