[Heathkit] SB-610 & SB-620

[carl]

Good Evening,

In the process of redoing both my SB-610 Monitor Scope & the SB-620
Scanalyzer.
Both tubes are "really" dim & traces aren't that good.
Voltages are good on each.. so don't think thats the problems.
Tubes have been replaced.
Believe both are getting "vintage .. like us all" & tubes will need a
transplant.
Are there any sources or does any members have the tubes ?
They are the 3RP1 for the SB-610, & the 3RP7 for the SB-620.
Thanks guys & 73s
