Hello everyone. I've just, literally half an hour ago, impulsively bought a Sharp GF-9090 off ebay. The Sharp GF-9090 Bought one in 1978 for the then very considerable sum of £200 ( £2.25 a week from Mrs Goddard's Littlewoods cataogue) which seems to be roughly what one in decent and full working condition is going for 40 years later. This was and still is a thing of beauty. This thing was my constant companion and assisted in shaping my musical tastes from the age of 16 to my early 20's. To this day, I still get a flutter in my heart when I see a picture of one. To think I will be the owner of one again soon is quite something. I've pipe dreamed with the idea of one day getting one and either gutting and converting to bluetooth or adding bluetooth to the existing system. (I'm hoping to do the latter) I have minimal electronics knowledge but am an IT Technician/gadget geek so disassembly and having a bash etc holds no fears. Description described it as not fully working with the cassette playing slow etc (I assume it'll be decomposing belts). I'm hoping it will arrive in a week or so. The first thing I want to do is order a bluetooth board for it. My first question, and I'm sure it will be the first of many is what output board should I be getting. I am, possibly wrongly, assuming that if I am going to tap into the cassette players preamp, I would need a very low output (or non amplified?) board than if i was gutting the case and feeding directly to the speakers. The speakers are listed as 2x3.5w and 2x5w, I've seen a Youtube video where someone has done this on the same model but it just shows it working. I've messaged to the poster so am hoping I might get some advice from them. Finally, thanks for letting me join. I'll be creating a relevant thread and any advice, tips, pointers will be very gratefully received. (And needed!)
Welcome to the forum, great boombox and yes they were pretty expensive back then. Keep us posted on the conversion, I don't you'll break anything if your careful, there's so many options to consider without going down a rabbit hole of options. There are a few members that have done it but I don't know if they want to share how they did it.
Thanks guys, I've been in touch with a Youtuber called Teddy Hashee, who I'd seen mentioned by the Youtuber who had added bluetooth to his GF-9090. He's kindly mailed me back and pointed me to a video he did on a Sanyo model... .... where the same principle will apply and he's happy to give advice as I go along so fingers crossed. I'll be ordering the bits I need and eagerly awaiting the arrival of the hallowed machine. I'll post more updates as I go. Thanks again
I posted a similar video in your other thread. A small tip. From a safety point of view it is far better to run the box of batteries if you are poking around inside.
