Hybrids or Frankenradios
#8

More comments:

I mentioned future plans to install a Model 89 chassis in a 32B tombstone cabinet. What I did not mention is: Having heard so many complaints about the autodyne mixer circuit used in Models 89 and 19, I have an idea on how to cure the trouble once and for all. It requires some modifications to the receiver's det-osc circuitry. When I find that elusive round tuit, I intend to use the 89 chassis which is going to be installed into the 32B cabinet as the guinea pig. If it works...I will dub it the "Super 89" and report my findings here in the Phorum. If it does not work...I will report that also. But I believe it will.
