The one that almost put me off this hobby! F**king Thing
I won it a couple of weeks ago for way too much money, looked very promising - until it arrived!!............
Seller (Forgot to mention) Oh I mean never stated the following:
Broken Handle
Burnt out mains transformer
Broken hinges on tape door
Seized graphic equaliser sliders
Two broken ribbon cable sockets (For graphic & indicator Led's)
Most of these bacame apparent after stripping it down to re-belt it, one of the faults the seller DID list!
This machine is a casualty of the end of the golden age - This 'Features' a cheap nasty cassette deck mechanism, very cheap crappy sliders, those horrid 'piezo tweeters' & a very cheaply moulded handle & cabinet
The beginning of the end of Sanyo for sure............
Add to that the sheer nightmare of getting this stereo working in any sense of the word & you might wonder why it never went straight in the bin! (It nearly did!!)
So:
Repaired handle the best I could.......
Replaced circuit protector on power board enabling the stereo to operate via the DC in socket (Power transformer properly destroyed, primary windings all open circuit)
Stripped out graphic Eq board & washed entire board in degreasing solution freeing up the sliders, then blanket re-soldering all the slider pins as they were so dry jointed that expecting them to work wouild be like trying to travel europe on ten pence a day & realising that it too, can't be done
Rebelted the tape deck - not quite as bad as eventually became a couple of years later but well on the way..........Tiny cheap nasty flywheel & a single square belt is all you get here with a solenoid crudely added to trigger the music search function! Yuk!
Desolder remove & discard the two ribbon cable receptors, clean the mainboard & solder the long (Thank Heavens) ribbon cable straight through the board to the clean connections I had prepared.......
With me so far?? I had already cut my finger almost down to the bone when cleaning out the front cabinet half - the tuner scale silver trim is razor sharp.........To be honest, it's lucky it didn't get binned there & then!! The fact that I paid way too much kept this machine in the running as far repairing it went...........
Graphic & Led board back in the cabinet, I cautiously plugged in my DC supply lead & discovered that 2 cables were plugged into power board the wrong way round causing the left channel to scream a very loud feedback type sound
I thought 'Oh shiat' the power amp stage is blown as is often the case with Sanyo stereo's (Ask a certain forum member for confirmation)
Anyway, everything cleaned up & before the rear cover went on, I performed a quick test of the radio & cassette with headphones to make sure everything was operating as intended before screwing case up & fitting broken tape door as best I can
Next Question: How does it sound??
Pretty damn good, not up to previous Sanyo mini generation models but all the same, considering the horrid tape mechanism, it sounds as good as you got for the later cheaper mini's!!
We all get nightmare machines sometimes, but this f**ker really pissed me off & is a real acheivement by anyone's standards & the thing is, despite all the problems I had with it, it works extremely well & does all it should while sounding rich & powerful for such a tiny stereo
Would I buy another?? NOOOOOOOOOO!! Never!!
I will sell or trade this one as it just does my head in looking at it!!
See & hear for yourselves........Sanyo M-7760K in red all working now!
