Does anyone out there have experiance replacing EL95's with EL90's?

With all these amazing table radios and consoles being produced in the late 1950's and 1960's, it seems that the EL90 gives out a bigger kick than the EL95's!

I found some threads and forums that describe a, 6BM5 as a direct replcement for an EL95, and a 6AK6 as a replacement with modifications necessary to the tube base.

The EL90 tube draws 45 vmA at 250 volts DC into a 5 K.ohm output-transformer, while the EL95 draws 24 mA into a 10 K.ohm output-transformer.So in many cases a direct replacement is not possible, also because of the higher heater- consumption and  the fact that the EL90 is taller.

How about a 6BM5/EL85 in an EL95 circuit?

The EL85 and EL95 are successors of the economical rimlock EL42 power-amplifier, designed for car-radios, having the same high tension and heater-consumption, with different bases. I have no experience with the EL85, but I do with the EL95 which was very common here.
