Thank you so much for this! I have one that I bought a 15 months ago, it's clean and everything works, yet purchased with the intent that our friend would go through it and check it. However, that was just when he decided he didn't want to service them anymore! Frankly, I have been hesitant to pair it with my FT DX-10. Your video was so informative, and with that I have the courage to bring the amp on line at very low power and see what it will do. Already decided to use a separate tuner (LDG 1000 Pro) and heat up the Cantenna. Just subscribed to your channel. Glad to see you are a "neighbor" over in Idaho. 73 AA7MO. 😀
Have repaired just one FL7000 with a trivial fault. They work best with the matching radios, the “band-data” cable makes it an integrated solution. Also controls the rig ALC so tuning does not happen at high power. The 1200w you mention is power input; output is in the region of 700w. A mate has had one of these a very long time, it took me awhile to understand the attraction of this relatively expensive and low powered amplifier….
You are a master at repairs and refurnishing as well as new build just finished the SKULLKRACKA rebuild 3 episode series seen one of them set ups at flea market on i75 but they wanted 2k for all 3 and You could smell the big box stinky of burned pills so I passed
Thanks so much for that video! I have and FL7000 that Bill refurbished and I love it! Now I know how to change the meter lights when they go out. Quick question I have a Yaesu FT1000D which no longer transmits. The receive is just fine but I was wondering if you would work on that since it is not an amp. It is the 200 watt version of the transceiver. You are just about the only one I would trust other than Bill to work on it. I was going to just sell it but from what I understand it is one of the nicest Ham radios ever made.
I'm working on a FL-700 now and I am strapping the input for 117 per the chart. I noticed in your video that the wires and jumpers appear to be connected to the same 117 and not the 110 VAC appearances that you mentioned. As I do want to wire mine correctly, am I missing something ? Thanks
Mr. BBI, do you still have the link or part numbers for those bulbs? I searched for "Marantz 12v bulb" with a few variations and I did not find anything that looked like what you installed. Thanks for the excellent video.
Your an intelligent fellow, very weldone in your thermodynamics explanation. I always admired Yeasu and their RF equipment, they were/are the pioneers in some of the finest communication equipment available. Do you recall those days way back, when you would turn something over and find a stamp that said "Made in Japan" truthfully, I miss seeing that, it sure beats seeing, "Made in Pakastan"!🤣👍 My Dad fought them during WW2 in the South Pacific on the CV-18, at that time, we didn't know shit about them, Dad called them Zombies with a tin can Navy..lol He sure liked their Ham equipment though.
Hi Manual says 1200 in 500-600w out anyway mine seems to have a control board issue because more than one relay turns on per band on low pass filter board and likely causes hi SWR and it trips into protection. Not sure what it needs. 10, 12, 15 meters it does 300-400 out with 25w drive but it will trip on most bands if you exceed 30w except on 10 or 12m. There is a hidden switch for 28mhz position B on slide switch on edge of control board when you tilt down front panel. I’ll have to call you. I suppose one could build a substitute switch to put 12vdc on each band to manually switch the proper relay so protection board sees good swr. I’d like to fixed so I could build the data cable and automatically track with rig. Suggestion?
todays auto tuner are very fast. then inside that amp remind me of the broadcast AM station tuner .it noisy but when set only moves a little to weather . snow hard rain effect loading a little. on a kw this is nothing but on 50KW it matters. no SWR on transmitter. just forward and reverse power with RF amps. the RF amps is what weather changes a little. 73's

If the auto tuner is microprocessor controlled and this thing is an older amp, why not replace the chip? with a new chip and updated code along with some nonvolitile memory the amp can jump to the correct tuning based on frequency. LDG tuners do something like this with their automatic memory tuners, cept those are faster with the relay switched tuning parts.

Nothing wrong with the tuner in this amp. I have one and run the tuner all the time and it flattens the SWR. I run about 100 watts from the radio through the tuner and then let it tune or tune it manually. Once SWR is flat then the amp is ready to be put in line. It's that simple. Why the hell would anyone drive the amp to full output and then try to tune it? Are they trying to damage the thing on purpose? Not rocket science is it. Pete WB4CGA
Wow that guy has fixed over 1000 of those, thats amazing.

Great video. Say I am looking for those lights, found on eBay. But are they 12v. Or 8v. A few to choose from. I someone or you can answer. Thanks 👍
According to the Yaesu manual, it is 1200Watt INPUT which corresponds to almost 600Watt RF out.
hi its a wery good peace of gear i have oane stord got replaced by vl1000 it stil works 100% did a full recap job 4 ears a go on it

600 pound in the uk ,,, great work mr BBI
A 1AND A HARF IS BETER STILL 🤣🤣🤣
Reminds you of something Kenwood would of built like there older radios with the tuners in them.
N4ATS is the world renowned expert on the FT 7000. Or was, anyway. He is now building the Mercury IIIs.
Its it just transmit?? I cant see the receiver anywere? Just Power Supply, Amp and tuner? o.O
Just like a car headlight. One goes out replace both. You know what will happen.
Perhaps they thought the "wiskers" would be good for heat dissipation?
Damn 7300 initial Key up Spikes

Where to buy amp lamps info ?

It's better used with an external ATU say some reviewers, to extend the life of the transistors.
They are wrong. Tune it with the output of your exciter, ie about 50 to 100 watts. Once tuned then press the operate button on the amp.
Ótimo vídeo trabalho gualidade total me

All amatur radioe's tune @5 or 10watt by
Default !! So tuner don't blow Up
You can't tune @1000Watt
Becaus when tuning... 10.0O0+++ Volt Will Jump the plates in the tuner!!!!
Thats why radioe's by default tunes @5 or 10Watt even tho IT is set for 100watt
No tuner is made to tune 1000Watt unless IT is big as a moovin cardboard case
Most 2000watt military tuners are aculey filled with inert gass as N2 nitrogen
Becaus sparks don't Jump as easy in a inert athsmosphere

The motorised tuner is slow but probably more reliable than a switched capacitor one…
@@g0fvt Yes, thus why I advocate to replace ALL the OEM circuits controlling the step motors. WHY? casuse a modern tuner is better!
