Hi everyone, thought I would share some pictures of my three Yamaha fully automatic turntables. P-700 P-751 P-850 All are fully functional. I just need another set of stronger hinges. They are all a nice match for the CR-840.

I just received a yamaha p 751three days ago. It was stuck on 45. Normally I would have focused on the switch, but this thread saved me so much time and effort. I ordered some resistors yesterday and and replaced R15 today and it was fixed! THANK YOU ALL! Tom

The 2250 drives the Fortes very easily. Regarding the use of a vintage receiver as a preamp, I did that several years ago with my SX-3800. I don't recall what I hooked it up to.

Yes, I am enjoying the whole setup! Marantz 2250 Marantz 6370q Klipsch Fortes

Thank you Paul. I ended up putting it all back together and I do not hear a hum. I hooked it up to my Klipsch Fortes as they are my most efficient speakers and it was dead silent! Thanks to everyone with their advice and encouragement, Tom

So I replaced the C401 and C402 with Poly caps, but now I have a grounding hum. I have not replaced anything else.

JD & Leestereo, Thank you for your guidance! Tom

Update: I purchased the parts to do a full rebuild on the P400 phono board. I replaced the 47uf capacitors for C403/C404. This was my first cap replacement ever! For grins, I hooked up and tested - the stereo output was restored! I am wrestling with myself on finishing the rebuild or staying...

Thank you Leestereo!

Thank you for the explanation! I was watching Blueglow Electronic's youtube video on this phono board. I think I will do a rebuild. It looks pretty straight forward. If successful, I will have the confidence, to tackle a Pioneer SA-9800 with a bad phono board. Thanks to everyone that shared...

I have not had a chance to measure DC, but here are some pics of the phono stage

Thank you. I will check tomorrow. What does it indicate when I change to mono and the channel volume comes up to match the other channel?

I have a meter that i am ok using and an oscilloscope loaned to me. I have not used it, but willing to give it a try.

Hello everyone, i have an issue with my recently purchased 2250 receiver. Everything seems to be i good working order after replacing the power button. The only issue I have is that I have a very weak right channel only using the phono selection. I have used deoxit to clean all the pots and...

Thanks everyone! Tom
