Default 33A-158M

Does anyone have the datasheet for these? I have acquired some but cannot find much info. I know from the usual Google search that they are similar if not the same as 6N7 but an actual datasheet would be great.

Thanks in advance

Not a complete data sheet, but some info:

CV1884 / 33A/158M

Not similar to a 6N7 at all. Different base, different amplification factor, different plate resistance.

Best regards

Thanks Thomas, I got the 6N7 idea from eBay. Probably the usual thing where the seller just makes stuff up to sell tubes.

Anyway they look useful. I might use them as drivers in a push pull amp or as finals in a small push pull amp.

Cheers Matt.
