If it is the later 550ZC model that is an excellent price considering that
massive external transformer.
OTOH 3 tubes a bit squirrely on 10M and removing one tube will make little
if any difference on any band unless you need the extra plate didssipation.
Ive used a two tube LK-500ZC since 1986 with the external PAC-5 and it
easily does 1500W altho I run at 1200W since that is the sweet reduced drive
spot for my transceiver for best IMD.

Subject: [Amps] Thoughts on LK-550
I have an opportunity to purchase an LK-550 in very good condition. The
asking price is $1300.00. Is this a good value? Thank you, W9OD
