There are 5 tubes of 4 different models, I've always bought mine from Danny as he sorts the best for his designs. I end up replacing mine once every 10 years.

the guy who is selling told me he replaced them 4 years ago







I suggest you send the unit to Danny and let him clean it up and bring it up to new spec, you'll have at least 10 years of service from it after.
