SVETLANA SV-811-10 or SV811-3 output tubes for ALTEC 1570 amps


Please only answer this question if you have first hand knowledge of this.........I would like to know if anyone has used the Svetlana SV-811 tube instead of the RCA 811-a tube in one of the Altec 1570 amps.....The plate caps coming off of the old style tubes is quite dangerous , so I'm thinking of trying the SV-811 because of the secure hook-up............Thanks Will
