I see that the TV chassis has a power transformer; so, that's a good sign. There were some BOTL color TV's from that time period that did not have a power transformer and were a series string hot chassis.
The tuner/amp looks like a BOTL model that's basically the same quality as a small table radio from the same period. The only difference is the addition of the extra channel for stereo.
Concerning tube type console stereo's, most of the major companies (Zenith, RCA, Magnavox, Philco, GE, Motorola, etc.) started switching over to solid state models by '63-'64. By '65, I think all of the "big names" had switched to 100% solid state designs. In '63-'64; RCA, Zenith, and others made some hybrid models that contained a tube tuner and a solid state amp. Some of the dapartment store brands (Truetone, Airline, Silvertone, etc) and some of the smaller electronics companies (Olympic, Arvin, Emerson, some Japanese import brands, etc) continued to use tubes up until '66-early '67. By '68, I think it would be safe to assume that all stereo consoles being built were solid state.
As far as solid state color TV's, Motorola introduced the first one, the Quasar works in a drawer, in '67. Then, RCA introduced the CTC40 in '69 and I think '71 was Zenith's first one. However, there were tube based TV's built until the mid '70's. In the case of TV/stereo combinations from the mid '60's to early '70's, it would be safe to assume that most of them contain a tube type TV chassis and a solid state stereo chassis.
