Cut the leads on the old ceramic, wrap the leads of the new cap around the post and solder. It's all too easy to rip the post out of these Jellypots.
Note the value of it depends on the model and the EHT tray fitted. 20KV versions usually have a 220pf, 16kv 160pf but check. Too higher value will give low EHT and excessive width, too low will give excessive EHT and lack of width with possible damage to the EHT tray. The same applies to the 1500 of course. John.
