Philips Miniwatt EZ81 - These are "da bomb" as the kids say... do they still say that? Branded Philips Miniwatt, but made in the Mullard factory in Great Britain. Philips owned Mullard, so it was quite common to see Mullard tubes branded this way.
These were in bulk packs, so they'll come to you in generic white boxes. We do not match rectifiers, but rest assured they are tested and screened to the highest standards.
Label may vary from picture above.
