Trio Kenwood KD-1033 turntable main bearing service

  One of my first posts in this blog was regarding the servicing of the Pioneer PL12D turntable, and that has proven to be the most popular by a significant margin. The Pioneer PL12D had its competitors, and probably the most popular alternative was the Trio Kenwood KD-1033 turntable. I use both names (Trio and Kenwood) as the company operated under different names in different markets. In the UK they were Trio, possibly because the brand Kenwood was most famous here for food blenders. 95% of a KD-1033 is similar to  Pioneer PL12D, and servicing them is very much the same process. Both are belt drive , have an AC synchronous motor,  mechanical speed change , a main bearing, sprung top deck and rubber motor mounts. the KD-1033 uses a different type of anti skate mechanism, employing a thread and weight. The plinth is shallower with an internal cross brace. One aspect that is different is the design of the main bearing, and servicing it is a little harder than a PL12D. The ...

Restoring 1970's Audiomaster Image Two speakers

 I routinely search ebay for bargain HiFi gear, usually once great brands now rather forgotten. A recent search yielded a pair of scruffy looking speakers but I recognised the old name of Audiomaster. They had been one of the 50+ UK speaker manufacturers that existed during the 1970's into the 1980's along with the likes of Tangent, RAM , griffin etc. Audiomaster were one of the first brands awarded the LS3/5a licence - the right to make speakers to that BBC specification, no mean accolade. The speakers in question were in a poor state, the tweeter looked heavily corroded, the bass unit had tears in the rubber surround, there were no grilles and the cabinets were quite scratched, but the seller made this all very clear. I put in a very low bid,  and won them for £3.  Collected from the nearby Town and the seller was great, collected and set about trying to restore them. First off after a bit of research I think these are Audiomaster Image Two speakers. The complex crossov...

Fixing a Karcher pressure cleaner that no longer dispenses detergent

I decided to clean some bikes during this unprecedented period of isolation, and got out a Karcher pressure cleaner we purchased some years ago for cleaning our decking. We have had it for 4 years, it works fine and creates a powerful spray which blasts the dirt off, and has a mode which dispenses detergent at a lower pressure first to fully soap the item, be it car or bike or garden furniture etc. However while the pressure hose worked fine I could not get any detergent to dispense. I checked the bottle which inverts onto a connector with a rubber seal. All appeared fine. I looked online via google and  remembered that the detergent only dispenses when the nozzle dial on the gun part is turned down to the 'Mix' setting. However I tried this and it made no difference. There are clear pipes which deliver the detergent from the bottle dispenser via a dial which sets the amount. I could see no movement through these pipes I decided to open the Karcher w...

Repairing a Bosch microwave oven with a rusty door

I'm ashamed to say that recently I noticed rust developing at the base of the microwave interior glass door panel, and the paint flaking. Cooking items like potatoes releases a lot of moisture , which probably should be wiped away immediately to avoid this, but when you are preparing a meal and everything you forget (or I do at least). The Microwave is a Bosch and has a face plate so it fits into a recess in our fitted kitchen. I looked into replacing the door but Bosch do not supply this as a spare, not could I find a donor oven online. A whole new oven would be around £300, which seemed a lot for a problem that might be fixable.  I read online about Rusty Microwave ovens, and advice ranged from " It'll be fine " through to " immediately remove the oven and place in a lead lined container at the bottom of the sea " type of response. Filtering the informed advice from the hysterical took a while. In the USA you can purchase Microwave oven pain...
