Hi all, I've attached a picture of the burned and new driver boards. There is a 1 ohm resistor on both. I hope the picture isn't too large for groupsIO. Bob W4JFA [email protected]> wrote:

Congratulations on successfully replacing the driver board in your IC-7000. Replacing those flex cables from the PA to the MAIN is a real challenge. Now for the reason I’m jumping in on this.

That sounds like a good idea. My 746 has a fan on it 100% of the time. Bob W4JFA [email protected]> wrote:

I have my IC-7000 body under the backseat in the factory storage tray.? As I mostly operate my radio when parked (don't want to run the engine) I use a 100Ah LiFePO4 battery - I get hours and hours

Got it done. Full power out on all bands. Old board burned. There was no heat sink grease on it. It looks like the heat sink design is good but why would they apply grease on everything else but not

Richard, That sounds great. I'm an electronics cooling nut. I have extra fans, or stronger fans on just about everything. I have an Icom 746 with a fan that blows air into the vent on the top 100% of

Hi Bob The 7000 notoriously runs hot. I have had mine for over 10 years and like a Timex watch it takes a licking and keeps on ticking. I keep a small fan blowing from the back

Geoff, Thank you. I'll start on the radio Monday USA eastern time. I don't know if the new board has the resistor or not but maybe I can add one if it doesn't. If the added resistor is the only change

Hi Bob, The driver pcb is not too difficult to get out and you will see the signs if it was the cause of the smoke. If your new driver board has the new resistor fitted you're good to go. But you

Hello, I just joined this group. I do not have a 7000 but am going to work on one for a friend. It let the smoke out so by reading it's a very good possibility that it's the driver board. My friend

Yes I have tried all modes on hf with no success. The driver should be good since vhf and uhf work correctly. I have ordered new finals so we will see if that corrects the problem. Thanks for your

Have you tried different modes? [email protected]> wrote:

Yes, it is possible, but I would look at the driver first.

I use a DM5AL separation kit. Works great. -- 73, WI6X ( https://www.qrz.com/db/WI6X/ ) Jim

I purchased a 7K with no power out on hf. ?Vhf/uhf are good. ?Receiver is in excellent condition. ?I have set the driver and finals bias and are good. ?Gate voltage of the finals measures 2.4V.

This aftermarket alternative worked well for me at a reasonable price. https://www.hamradio.com/detail.cfm?pid=H0-018630 73, Paul WA1VEI
