6N1 substitution with 6922
Looking at these 2 double triodes it would seem that the specs are pretty similar. The exception is that the heaters draw less current on the 6922 and that the anode voltage rating is 250V for the 6N1 and 130V for the 6922 (ECC88).
I've checked the anode voltage on my amp and it came out as 90V on one tube and 100V on the other (i.e on one tube I got 90V between triode 1anode and ground and 90V between triode 2 anode and ground). So 90V or even 100V is < the 130V rating for the 6922 so it should be OK to use, right? So could someone double check me and see is there any good reason why I couldn't use a 6922 in place of a 6N1 both tubes are at www.tubedata.org TIA, Fran |
