[R-390] OA2 Rectifiers

[Gene Dathe]

A few weeks ago I posted one about why you would want to replace the OA2 
rectifier; never goes out, never heard of anyone with a problem ,etc;...

                           ---I stand corrected.---

Since that time I have replaced the 26Z5Ws and the OA2 in my R390A with 
Weber Copper Cap solid state rectifiers.  I must say the difference in 
generated heat and power consumption is astounding.  REALLY reduces heat.  
Of course I can't say much for the life of these devices.  I can say that 
the Weber rectifiers are a worthwhole investment, considering heat and power 
savings.   They are relatively expensive, but 26Z5W's are expensive too, at 
least on Ebay.   As always, my comments must be judged if you are a 
"Practical User" vs. "Commited Collector".   The collector will find the 
Weber rectifiers to be a quick and painless way to keep their vintage 
equipment operating.  The practical types know the stock diode conversion is 
certainly acceptable.  The Weber Copper Caps allow you to retain the look 
and feel of tubes... for SOME this will be a very agreeable modification...
