Vacuum Tube - KT88, JJ Electronics

I am using 6550a tubes in a ham radio modulator can I use these KT88 tubes to replace the 6550A tubes and if so will I squeak a bit more power out of these???

The KT88's are similar in construction and power to the 6550's but they may not be drop in replacements depending on the unit. I would suggest referencing the spec sheet for both found on the product pages for absolute compatibility.
