New to me Old Ham Transceiver

I just purchased an older (mid 1960's I think) Kenwood TS820S ham Transceiver. Its hybrid, both solid state and tube. I haven't plugged it in yet, but other than visually inspecting all the caps and bringing it up slow with a Variac, any ideas on what else i should do? Oh, and no, I am not a Ham (yet), and yes, I know not to transmit without an antenna load... or without a license for that matter.
thanks
Tom

Actually this is late 70's to early 80's tech. :wink:

Here's the service manual, if you haven't down loaded it already.

I see these and other Transceivers a lot at Hamfests.

I didn't get into being a Ham myself.
But I did do a lot of citizen band radio {CB} in my younger days. :roll:
And Yes,
Do Not Key Up The Unit{Transmit} With Out A Antenna Or Antenna Dummy Load Connected!
You can blow out the Transmitter Finals by doing so.

Here's a video on tuning your rig.

Also check on what the manual recommends for an Antenna.
Here's the operators manual.

And here's a place that carries parts, and does repairs.

Have fun with your new hobby!

Great Information, thank you!!!
I dis CB stuff in while young, then some comms stuff while in the Coast Guard years ago, HF RTTY and VHF and HF voice stuff, so I am not completely clueless, but certainly close. I have a good friend who is a ham wh has been egging on for years and when I saw this rig it seemed like a good idea. I'm just going to do a physical inspection, blow the dust out and bring it up slow with a Variac I guess. It it "poofs" I'll try to post a video!

Thanks again

Tom

{Slaps forehead} :lol:
I forgot the most important website!

ARRL, the national association for Amateur Radio
http://www.arrl.org/

You'll find a wealth of information on local clubs in your area.
As well as help from people who are far more knowledgeable than me, on HAM equipment.

the vacuum fluorescent display says newer than 60s. it surely also lacks tubes (but then what is the heater switch for). I think I saw equipment like this in the early to mid 80s. Nice looking box.

because tubes are hard to beat for transmit output and driving the output tube. Everything else in the unit can be transistor or LSI ICs.
