Thanks for coming to our store
1pcs = 1pcs (screen flow) (transconductance) dual pairing
2pcs = 2pcs (screen flow) (transconductance) dual pairing
4pcs = 4pcs (screen flow) (transconductance) Matching group
Buy 2pcs 4pcs 8pcs=precise matching (matching group).
Regarding the matching, all of our tubes are matched in the factory production workshop. The matching is accurate (not all tubes have been matched). We have the conditions and advantages to match multiple tubes (four, eight, ten) according to customer needs. The parameters of the two tubes are the same)

At the same time, 6550B can also be used in electronic voltage regulator circuits. 6550B is similar to KT88 and can be used interchangeably.
