Is it considered acceptable to replace a lug style cap on a main power board with a radial cap? My Pioneer SA 6500 Mk2 has 2 6800uf caps ( 42v) with lug spacing at 22mm. I dont see any replacements available on Mouser or Digikey that come close to those lug measurements. I do have 2 6800 uf 50...

A local seller that I have been buying projects from the past few years has a couple pair of EPI M201s that have caught my eye. Right now my main setup is my restored Pioneer SX850 , Dual 606cs turntable and Teac 2300 RTR running through a pair of the NLA Advent speakers. I really do love the...

Hello, a couple of years ago , with a ton of help from folks on here , I was able to bring my SX 850 back to life. Looking at my notes , seems I had ended up replacing caps and a few transistors on the power board to get it out of protection mode and then recapped the tone amp board to clean up...

Hello, I need to replace the lamps for the VU meters on my SC 5330 tape deck and was wondering where I can purchase replacements. The lamps are inside the VU meters themselves and I believe they are rated at 8v and 65 Ma. They are soldered in and not the fuse type. Any help is appreciated! Thanks.

So I picked up a pair of these Klipsch KSP-300s from the original owner. Both speakers had the dreaded 60hz hum coming from the subs. So far I,ve replaced all the caps ( electrolytic) on both power boards and both amp boards. The 60 hz hum is gone and both these speakers sound incredible...

I,ve had this 7240pe for many years and have enjoyed the power it puts out, but its run into an issue that may be terminal. A few months ago while listening to the turntable the sound cut out. I pulled the NAD out of the rack and hooked up the Pioneer while I looked at the NAD. After opening it...

I need to replace the RCA cables on my Dual cs 606and have a question. I,ve loosened up the 3 transport bolts and the plate holding the cables in the back, but the main plate will not lift out. I watched a vid on youtube opening up a Dual 505 and the 606 seems similar. Am I missing a step on...

After receiving a ton of help on AK getting my Sansui QRX5500 back up and running, I thought I would post a quick thought on this unit. I finally have it hooked up and have tried different speakers and turntables looking for a good match for the QRX. As of now, its running a Dual cs 606...

Last year I did a recap of a Pioneer SX850,and the an SX650 , both with help from these forums. Both units would turn on and then shortly after go into protection mode. As suggested by the folks on here,the first place I looked at were the power/ protection boards.I replaced caps and transistors...

I recently recapped and replaced the transistors on my Pioneer sx850 and sx 650 using replacement lists found on here. Both units are working wonderfully. I,m getting ready to recap the power and driver board on my Sansui QRX 5500, and using the service manual can find part #s for the...

I,ve had the RG-9 sitting on the shelf while restoring my SX 850. Now that the SX is up and running I would like to try setting up the processor but am a little confused on the proper hookup. Has anyone set one of these up on an 850? Just wondering what plugs into where. Thanks ! Chuck

Just wanted to give a way overdue thank you to the many folks on here that helped me walk through the restoration of my sx850! It was definitely a learning experience and it was a slow process,but all boards were rebuilt per Marks parts list and the 850 is sounding fantastic. A while back I...

Ok, this may be a stupid problem and I may be missing something but I have to ask. Just rebuilt my flat amp and started the tone amp. I replaced both q1 and q2 on the tone amp....but here is where I,m stumped. Looking at the schematic on the SM, the tone amp schematic just has me scratching my...

Just finished replacing transistors and caps on the SX 850 protection board. I had previously changed out the transistors and some of the caps on the power board. I finally have a good relay click and sound from the unit. However I have noticed that even with the volume down,there is distortion...

I think "Markthefixer" posted a full list of replacement parts for the sx-850 protection board a while back..does anyone know where that link may be? I,m just going to save myself from multiple posts and rebuild the whole board. Thanks ahead of time! Chuck
