Re: Non-matching output tubes in HF81

I do not have an HF-81 in front of me...but I took a look at the schematic.

Each pair of outputs has its own cathode bias setup (ie- resistor and cap).

So you should be able to get away with putting a MATCHED pair into each channel.

Since you imply in your post that you have 2 matched pairs, you should be fine.
