Parasound p / SP-1000 Repaired.

When i was really really young and into audio i dreamed of owing a Parasound Pre-amp.

I went searching on Ebay and found one for 199$ 🙂 YES it’s old but it’s a good one. I searched google for hours for photos & information on repairs etc etc and found nothing.

I bought this, thinking it had no issues but it did, that’s ok I have PAPS to help out..

I connected it and it sounded like POOH..

Fixed now though. It had a pair of 2SC3327 muting transistors shorted on the output. After using the scope to hunt the issue down and replacing them all is perfect.. Now to find a remote…

Pictures of the output on the scope,

Front of the unit,

Inside, with a very nice heavily regulated PSU.

AND my messy Bench!

Have to thank my dad for helping me solve the issue and teach me some scope tricks.

Now to poke at it more and do some upgrades change all the op-amps & some caps & resistors.. Maybe cleaup the regulated PSU ….

New Site & Topics

Well, it’s been a long time since I have posted on here. So i’m doing some updating and posting. First, you should have already seen that I changed the name 🙂 Second, I am no longer flying R/C Heli’s Jet’s & Planes. I sold it all and go out of the hobby, so many reasons but no need to go into them.

So I’m back into electronics & audio.

I’t been a long time goal to finally build some very nice speakers from scratch again to finish. Although i won’t be building the cabinets, instead i’m going to have a VERY good wood working friend build them for me, just so they are perfect and exactly what i want…. I’ll create a post soon and keep it updated.

Next goal was to finish my 2 channel pair of Aleph Mini’s. So far im 90% done, just have to do a bit of chassis wiring, then i’m done. They have been running for over 10 years and work perfectly just needed chassis.

Another goal, was to actually buy a good Oscilloscope & learn to use and understand it properly.. So i ordered one 🙂 will post info about that here & my youtube blog too..
