this is almost the same scenario as here in AU with DickSmith Electronics stores, in the 80's they were bought out by Woolies (Woolworths Limited - no association with Woolworths UK) for a while, right up to the end of 90's they kept the format pretty much the same, hobbyist and electrical components stores for enthusiasts!
However end of 90's the average customer wanted more, and with growing competition from Harvey, GoodGuys etc etc. Woolies decided to change the format in order to keep the shareholders happy and make profit by selling TV's, consoles, PC's, Apples, Ipods.
They stopped employing clerks with knowledge of electrical components and started to employ sales men instead. Changed the store layouts and the type of stock.
On one hand all the better for shareholders as they single-handedly killed off their biggest competition, Tandy Australia, and bought them out.
Woolworth's Electronics people have dubbed it these days. My local store the only electronics person is the manager, he's battling to keep some of the tools (like the compressed air spray) on the shelves.
On the other hand it only leaves us with JayCar Electronics, almost all of the sales people are "geeks" (which is a good thing!) or eBay.
You're not been in Jaycar lately obviously, its full of sales drones now, with a token electronics person somewhere in the store. Plus the prices went up on everything a few years back.
So I now shop for electronics online, or at the (one only) independent city electronics shop. With the Aladdin's cave of spare parts out the back, bits and pieces all over the counter, bins full of DIL sockets and IDC connectors. Yak about your latest project, the TV your fixing or whatever and they know what you are talking about.
