6H6/6AK6 to 6H6/717A converter

Hi all here are photos of a 6H6/717A converter I built recently. The 6H6 is parallel connected to the anode of the 717A. Filaments parallel also.

Here's the converter in action, hooked up to an APPJ 832A amp in parallel with 6AK5's.

The rig has a wonky g1 on the pre-amp tubes. It's hard to tell the difference from it if it had a bypassed cathode resistor due to the nature of the great psu.
