The 2 pill 2sc2879c with a built in low pass filter will do 500 nice and clean on the spectrum analyzer, throw in a true regulated ab bias circuit and you have ham level performance.
The 2879c is not the same as the fakes tx star was using. The fakes work with only minor tuning changes to the circuit. The 2879C requires different winding of the input and output transformers to function properly.
Try a 68 ohm or around that, usually they end up between 33 and 150 ohms. I do not like that swing mod myself, not much average swing and does not look good on the scope. The better mod uses a tip120 transistor a 220 ohm electrolytic a 100 okm resistor and a 5k to 10k potentiometer to set the...
The Hg 2sc2879C Is a whole other animal Than the Toshiba 2sc2879. I have a Texas star 1600 with toshibas That will key 100 with 2 watts drive. I have a Paladin Tx-800 with 4 Hg 2879c that will key 100 with 10 watts drive. At vehicle voltage.
The built in speaker is a big thing for some of us, and for those who say the built in speaker is no good I added a speaker with a better cone and larger magnet in my 2517 and have been very pleased with the sound quality.
I like the new 29, a lot of the 80s mobiles have dried out caps a recap would cost more than a new 29. I like the receive and transmit on the new 29s vs the later am only models. If you want to use an expo kit it will NOT work on the am/fm
At least good service info is available to put them right.

The roseta stone of radio repair for a new tech
I work on radios every day for a living and while I like the features of the areas II and the like but I do not find the digitally processed sound pleasing to my ears. I would rather work on my person radio with a soldering Iron and a gc alignment tool than a usb cable and service menus. Just a...

It looks like the ranger made classic, maybe a distributor in Europe has them.
You are correct, when my amp guy bought a big shipment they offered him either dei or hg branded transistor that were the same part, He chose hg branding because of the bad reputation with the early dei parts.
