[Heathkit] SB=220 Graphite Mixed

[jeremy-ca]

Ive had many SB-220's come thru here that way and they all worked fine with 
no one tube doing power hogging.

Is it ok to mix a new graphite 3-500zg with an old 3-500z?

I need one but not two.  Or does anyone suggest replacing both?

Is there a distributor you suggest?  Matched set or no.

Thanks, any help would be appreciated.
