After I opened up the DB-2 I went looking for info on the Reichenbachs and found that they share a common lineage with Jensen. Reichenbach manufactured the Jensen parts until they parted ways. Stories I've read differ on who did the design and who screwed/copied who after the split. Some of the transformers are identical except for the prefix of the part number. The later designs from the two very likely diverge. Maybe the new Jensens are better than the new Reichenbachs.
You have sweet transformers regardless of which name is inked on them.
Go tape something.
