ECL85 = ECL 805 ?

Hi,

 

Can anyone explain me if there's a difference between ECL805 and ECL85 ? They look so similar and internal values also. Am I right or wrong ?

ECL805:
Pamax= 8W (10,5W with fixed grid bias)

ECL85:
Pamax= 7W (9W with fixed grid bias)

PCL85/PCL805 have the same limits.

In some later documents the PCL85 is listetd with the same limits as PCL805. I am in doubt that that is really correct. But perhaps the later 85 types have got the construction elements of the 805 types, too.

The 805 types are redesigned 85 types, because the 85 types often failed, and because a stronger version became necessary with the start of colour tv in europe.

Hi,

many thanks for your answer. What would happen if I replace ecl85 with/by ecl805 ? Can it damage the device ?

If you replace an 85 type by an 805 type, then there will happen nothing. Due to both types have identical characteristics (except of Pamax), it will work properly. But you should be careful when replacing an 805 type by an 85 type: In most cases it will work, too, but the 85 type could fail earlier than usual.

Dear Matthieu,

due to reliability Problems the PCL85 (Pa= 7W [1]) became the successor PCL805 (Pa= 8W [2]) where nothing else had been changed except the pentode power rating.
For the same reason the pentode part had been put into a single envelope, which was named PL805 then (with "E"-Heater also produced as EL805).
The following article from "Funkschau", 1967 Heft 1 page 16 is showing this.
