The 25" is 19kv; however you do usually need to turn up the pot to get it to
19kv. The 25" probably has more resistance?

If anyone has a 25" colour Vector monitor and a good HV probe I'd
appreciate a reading...I would rather limit the HV to around 20KV, but
Ampliphone doesn't mention the rated HV in the manuals I have for the 25
inch tubes.

19Inch tubes are 19.5KV...
