G8000 in for a few small jobs and prospect for a full job later on.....

kevzep

Its all about the Music
Here we go, a nice G8000 with a custom wood case, not veneer!! Its the full wood deal!!

Tuner is distorting and not tracking, unable to tune the stations properly, tune meter is showing offset all the time.
Keeps cutting out on one side.
Check over, bias+DC offset.

Need to get that BA-F1 off the bench before I look at this though...

I had to put the BA-F1 aside to get this job done urgently for the customer.

Here's a few pictures of the case, its really nicely made.
I took the connected/separated switch out ready for dismantling in the morning, then the tuner will be aligned, a check over, DC offset and Bias checked. I will be recommending we do the full re-cap, relays, and so forth....Its actually a bit rough this one, but seems to function okay, however in its current state its days are numbered.

Nicely done case, though that looks to be Baltic Birch plywood, not solid wood. Still, Baltic Birch is a high end plywood with even thickness plies. A great finish on it too!

Yes once I got the case off I realised it was ply....It does have a great finish!!

The tuner was a bit of a mess, I had to take the Front End pack out, and rebuild the Variable Cap on the LO, It was falling apart, and also one of the RF Gang trimmer caps was broken, I rebuilt that from a spare Tuner I have for spare parts.
So pulling the front end apart not exactly very simple, had to basically restring the whole thing as there was a whole lot of grease all over the dial string.
Then I found that every possible thing that could be adjusted was in fact "fiddled" with. The dial tracking was out by 3mhz thanks to the broken LO trimmer cap, and the dial string which had been installed badly and the dial pointer wasn't secured properly so it was slipping on the string....
It took me twice as long to align this tuner but it ended up turning out quite well. The FM Stereo indicator is out, so I am going to have to find an original type to buy from a parts unit, they are special type which is not available new any more.
The customer uses the tuner, so I should imagine he'll be quite happy with it....
I didn't take many pictures as the job was pretty intense, but got a few after the job...

Nice work Kev!

Re the stereo indicator, is it a red LED with a stepped down diameter to fit into the small front panel hole.

Cheers

Thanks John, I know the LED you are talking about, but it is not one of those ones. They in fact have a clear lens on them, odd looking LED's...never seen anything like them before, but the G series receivers used them almost exclusively...

Hi Kev,

Does it look anything like this

You know what, I think that might be the one there John!! What is that out of?

Hi Kev,

I believe that it is out of a G5000 or G6000. The board assembly is a different part number compared to a G8000, but the part number of the FM led assembly (the circular black housing) appears to be the same for the GX000 series. Let me know if you want this, happy to send over to you.

Cheers

John

Hi John, That would be great, the owner of this wants me to do a proper repair to it and swap the RF Front end out. This was I can get two birds wit one stone!!
