Finally fired up my newly acquired SX-1050

After waiting what felt like a lifetime I finally managed to transport my SX-1050 from the west coast back to the prairies. It was roughly 2 months in the making but I managed to not damage it. Took the front panel off and cleaned up all the knobs and face plate and dusted out the insides and I can confirm the unit I purchased is indeed virgin and not abused in any way. No burn or scorch marks and absolutely no signs of prior tampering. Short of a couple of slightly bent switches and a scratch on the faceplate by the tone switch that the unit is working perfectly. Been playing some for the past hour or so and no heat issues to report on. Unit looked like it lived it final days with the previous owner in a woodshop or garage as it has sawdust all over the front of the unit. In any case I didn't even have to Deoxit the switches. All switches and pots work flawlessly. Sans the scratch on the front panel and nicks and dings on the wood case overall the unit is not bad at all.

Although I've only been listening to music for roughly an hour or so that I can say for an original 40+ year old ampler that it does WONDERS to the sound. Not too laid back or warm but not clinical. Separation and detail is very good and it has a bit of an airiness to it. It will be very interesting to see how the 1050 will sound and perform once I've given a new set of caps and transistors.

Would you folks recommend that despite it working perfectly to only change the caps or SHOULD I change the pre-amp transistors as many have suggested along with a few resistors? The insides LOOK new but obviously with 40 year old caps that there is bound to be drift.

Thanks!
 
if it has 725's and 726's and any others on the 10 most wanted list you would be well advised to get them out before the fail and damage things. i rebuilt a junk 850 and replaced all the silica in it and it sounds really nice. it should play for decades to come
 
Oh I am certain it does. I just fired it up to play music while I compile my list of parts I need from Mouser. What is this top 10 list of bad transistors you speak of that I can refer to?

Thanks

Thanks TSD71.

I will convert this list into a BOM so that I can place my order with Mouser hopefully tonight :)

BTW I don't want to mess with the tuner b/c it would otherwise need realignment but are there ANY powering parts that I could change on the tuner board that wouldn't impact the tuner's precision but would add more life to it?

I ran all the part #'s provided by TSD71 and the following parts are not available from Mouser or they want a subbed part. Any suggestions on a substitute? I have included the Mouser part #, Description and which SX-1050 amplifier board it is referenced to.
Thanks!

I and others have written many times that these older lists have obsolete comps in them but if you search Mouser using the device parameters you can find close alternatives. There are other posts where members have included replacement part numbers for those caps basically devices on 5mm lead spaces will do the job.
 
Hey RCS16, yes I took the time to sub in certain parts however, the specs are slightly off (voltage wise) than what I need.

For example the film caps don't come in a 0.22uF @ 50 volts instead there is a 0.22uf @ 63 volts. What I'm not certain on is it better to oversize voltage slightly or oversize capacitance slightly? I do have a "subbed" list of parts I will be posting here shortly for others to review before I pull the trigger an place my order.
 
What power filter caps do you folks recommend to purchase from Mouser? This is what I came up with but I see that MattSD on his website used 22,000 uF 100volt filter caps and not the factory standard 80 volt versions. Is there any advantage going to a 100volt main filter cap?

The part I found on mouser that meets what the factory sizing is the United Chemicon caps part # 661-E32D800C223MD79M

From my experience, certain caps of exacting values to your originals simply don't exit much these days and so keeping the capacitance the same but with slightly higher voltage is totally fine. The tech heads refer to this as "more headroom".
The 63v in place of a 50v is ok.
I'm happy to be corrected on this, but I do recall replacing several caps with higher voltage spec and have had no issues.
