(Guest)   2   Hello Mietek, over the decades I used several pairs of the 6146 family, such as 6146A, 6146B and the rugged 6146W. You only have to re-neutralize the PA. Don't mix different tube models, always use a pair of the same tube type. Depending your power-supply, I would prefer the -B or -W tubes. Those can work better with Ua over 850V DC. There is a difference in Plate Dissipation: the 6146, 6146A and 6146W 25W, the 6146B 35W 73, Michael Schlör DJ8IJ This article was edited 05.May.06 15:52 by Michael Schlör .

Mietek Jozwik   PL  Articles: 11 Schem.: 0 Pict.: 4 08.May.06 10:42	You aren't logged in. (Guest)   3   Hi, thanks for answer. The problem with that tube is they are practically not available in Poland. So I am looking for replacemnt. Some TV's sweep tubes looks similar in catalogs but dummy replacement can fire out nice old piece of equipment.

Michael Schlör   D  Articles: 75 Schem.: 262 Pict.: 108 08.May.06 16:05	You aren't logged in. (Guest)   4   Hello again, DO NOT use any TV sweep tubes!! This will damage your SB102!! If they look similar to the 6146's, for shure: they are NOT the same. The tube data will be completely different! It's very difficult to redesign the PA-tube configuration for a sweep tube as well as the Pi-network! The only replacement-tubes you can use are: 8298A or QE05/40 or YL1370. These tubes can be used by only neutralizing the PA. 73, Michael Schlör DJ8IJ To thank the Author because you find the post helpful or well done.      Help
