"It sports 35 watt plate dissipation"
The datasheet says 27. This is the same as the 6146B.
"beefed up screen voltage"
6146B - 250V
6883B - 250V
6146 - 250V
In fact, the datasheets for the 6146B and 6883B are nearly identical.
The heater voltage/current looks to be the only difference. Even the interelectrode capacitances are the same, and it doesn't take much of a design change to throw one of those off by a tenth of a picofarad.
