Yes, that's what I think it is.
I started with a $7 chinesum amp from Amazon or Evil-Bay, fed by my agile modulator. Rated 2W output @ 12v, about 1.5W @ "safe" voltage of 10v. Lovely harmonics. Filtering is a must!
The big problem is that there's impedance mismatch between the 75 ohm modulator and the 50 ohm amp input. What transformer would you suggest?
I know RF-Links has 75 ohm TV amps though. I'll have to see if they're within my budget.
