Fender produced the "30" amp from 1980 to 1982. It is from the Rivera era, and I believe is the last of the point-to-point wired Fender amps from their standard product line.
They also produced a big brother to this amp called the "75" which was switchable to 15 watts.
These two amps are among the best kept secrets for harp amps. As this video by Victor Doors shows, the amp is rather clean but warm and full. With a little tweaking it can sound really good.
Several months ago a friend who lives in another state (and who is a talented blues harp player) found a mint Fender 75 for sale in Denver and called to ask me to go try it for him. I did, captured it on video which I sent him, and he bought the amp.
The Fender 30 and 75 were not big hits with the guitar guys, which keeps the prices down. They are not common out there, but the prices are usually from around $400 to $700.
There is a Fender 75 with 1x15 for sale right now on eBay:
I own the two smallest Rivera point-to-point Fenders: the Super Champ and the Champ II. They both feature 18-watt, dual-6V6 power sections and 10" speakers. The Super Champ adds reverb and a "Lead Boost" circuit which the Champ II lacks.
I intend to sell the Super Champ -- it's more suitable to guitar, I think -- and then maybe tube down the preamp in the Champ II.
+1 on Yale-great for harp or my baritone Tele Also have Champ 12 which I always back off selling but really never use
