Subject: Veronica 20 watt amp smokes !! From: L.D.Brewer Date: 1997/03/27 Message-ID: <5hfhma$9jq@lori.zippo.com> Newsgroups: alt.radio.pirate NOT Literally ! No the amp didn't smoke... But not for a lack of trying!! Our evaluaton is complete on the Veronica 20 watt amplifier. We tweaked it , peaked it, let it run for 3 days without a fan, and it STILL puts out 20 watts. Even after OOOPS ! I forgot to hook up the dummy load ! This design is based on the BLX 69 transistor. ( I can hardly read the thing ) This data may be wrong ! Anyway, our test unit was tuned up to 100.00 as a test frequency. We drove it with a Veronica 1 watt PLL. This cute little design is built on a 4" X 3" approx. heatsink with 2 SO-239 connectors on top. We would have thought that the heatsink would have been too small, but since the device develops less heat than the BGY based stuff, it seemed that it was happy with this much dissipation area. As small as it is , the amp has a reasonably good gain considering the 1 to 20 factor in overall amplification. How about the harmonics ???? I knew you would ask that ! ! The amp was supplied to us with a funny looking cable which was supposed to be "to assist in the elimination in harmonics, etc. ".... So to the spectrum analyizer we went... -50dB on seconds with the suppied cable....- 50 on second order harmonics with a piece of crap jumper we found laying on the shop floor! Overall, and since we tested this with the Veronica PLL, its about as clean as you can ask for in the price range. Filtering required ??? Naw ... Just use a good exciter with one watt of drive. Fan required??? Up to you, we suggest it whether you like it or not, but ours didn't even get hot enough to fry any e ggs. As usual, Veronica supplied a tuning indicator LED, so you can tune the ONE little variable cap to the correct frequency without having to buy a wattmeter. COST???? Well I can't say ... About $150.00US built. Veronica does not want to sell the item as a kit. Availability ??? Probably about 1 to 2 weeks before the stock starts rolling into the US. Please call the shop to gather more information ! As usual, Veronica FM has provided the people with a reliable piece of equipment at a reasonable price. Order now...Operators are standing by !
