I'm in need of several Holco h2 20k 1w resistors. I've bought the last of Part's Connexion's stock and they will not be getting more due to the change in the manufacture of these resistors. Or, would anyone care to offer their opinion of a good replacement for the Holco's. By the way, these Holco's are .5% tolerence, metal film types. The aplication is in a tubed feed back loop of a hybrid amplifier, so precision and very low noise is a must. The Holco's seem to work well even though they are not that expensive.
