I have a Willsenton R800i 300B 805A 48W amp and I order a complete set of tubes for it. My question is. I ordered 805 tubes not 805A. They look the same. The Cossor 805 are the tubes that i purchased and was wondering do I need to return them?
The 805 and 805A are internally similar except the Anode, in an 805A, connects to pin 3, not the top cap.
Nice little transmitter valves. Used many years ago in telephony work by various telephone companies.
The 805 has 10volt heaters at3.25Amps and is the predecessor of the 813.
Hope that helps. Attached is a photo;

Those are the correct tubes for your Willsenton, yes. The Chinese 805-A does NOT have the plate cap so it's a little confusing.
Hello ,I had newly acquired, I was also thinking about the 805 with the plate cap, there is a hole for the HV on the chassis on each side, probably for connecting to the anode plate using a cable which connector (?) which is not supplied.
any idea?
Thanks
