    Marantz 2325 won't isn't reading any voltage at P800 voltage regulator pot after recap.

    Nope to both, I'm resoldering a couple of traces that may've lifted on a couple capacitor legs. Changing the fuse to be sure and will report back. Somebody before me got to this 2325 and did some pretty bad work. A lot of solder bridges, and jumpered traces on boards.

    Marantz 2325 won't isn't reading any voltage at P800 voltage regulator pot after recap.

    Been working through the many issues on this Marantz 2325. After sorting through problems on one of the amp boards, I'm having a problem with the P800 board. I'm not seeing any voltage at pins 804 and 805 when I should be seeing 35VDC. The relay is clicking, just no voltage at the two pins. I...

    2325 left channel weak for all inputs in 'source' position...

    I seem to be having a very similar problem with a 2325 that was on my bench to recap. I'm going to look at the PH01 board and see if that can remedy the similar complaint.

    Scott 222B advice needed

    I just noticed that my phase inverter tubes are 6U8 and not 6BL8 like the schematic shows. Would this be a problem with voltages being off?

    Scott 222B advice needed

    I tested the phono section, (before recapping), and it sounded pretty thin, very little bass compared to the Extra input with CD player. I put some Telefunkens in that position as well as the preamp. Tested phono with those 12AX7s and some good JJs but no change. I hope this gets improvement...

    Scott 222B advice needed

    OK, I did remove a similar wire attached to the auxillary and fuse holder on a Sherwood S-5500 II I rebuilt a few months back. Sounds dumb but how and where would I measure current draw before and after I install the CL80 to confirm I'm getting a drop in voltage?

    Scott 222B advice needed

    Do you think a CL80 could attach where the gray wire is coming from the auxilary to the fuse holder, just replace that gray wire with the CL-80?

    Scott 222B advice needed

    Is there any need to install a CL-80 since it has a rectifier tube already, and if so where exactly does it connect? I am guessing it may be tied between the primary wire that attaches to the fuse or the auxilary plug receptacle.

    Scott 222B advice needed

    OK, good to know. I ordered a kit for the 222B from Hayseed Hamfest, hopefully that can will be insulated.

    Scott 222B advice needed

    I went ahead and switched the 6U8s and replaced with NOS RCA black plate. That didn't help it. I didn't check to see if that Bias can heats up, could be one of those sections. I cleaned the sockets, switches and pots with Deoxit and Faderlube.

    Scott 222B advice needed

    I cleaned all sockets and tensioned them as well as possible. Switched the power tubes from left to right side but still has the startup crackle. Could this be the on/off volume switch acting up? I was wondering what voltage that large orange .01uf deathcap is? What do you think I should...

    Scott 222B advice needed

    Thank you for this link on the crackling problem. Mine is making that crackling sound on startup only on left channel, not right. It too has a lengthy startup time. I noticed if I changed the 12AX7 I got a change in the noise problem, not an elimination. I'm going to start by cleaning all...

    I'm sorry, I'm not familiar with tie points on output tube pins

    Scott 222B advice needed

    Thanks Dave, I'll clean and retention the sockets and give it a try. Can the 222B use 7189s?

    Scott 222B advice needed

    I bought a Scott 222B recently in working condition, had some static noise in the left channel that would appear on startup then calm down. I checked all the tubes and have been replacing the obviously bad ones. On the preamp side if I'm correct, one 12AX7 socket (V2) is missing the Pin 9...

    Harman Kardon 930 tone board debacle

    It beat restringing the tuner. But it is risky. I personally didn't find it was putting anymore strain on the shafts or board traces than most other ones I've pulled. It is just a PITA receiver to work on IMHO.

    Harman Kardon 930 tone board debacle

    Got the lamps working, seems I overlooked the jostling effect on the function lamps underneath the tone board. Didn't realize I didn't have dial lamps with anything but FM or AM selected. On a high note, I found 2 closely matched pairs of 2SC897s and was able to stabilize my bias at 15mV...

    I replaced outputs and the DBT dims when the speaker load is pushed in after powering on. Now I've lost my lights for some reason.

    Harman Kardon 930 tone board debacle

    holy crap that looks like fun. I think I remember something about the speaker load thing now that you mention it. I pulled the outputs and they weren't shorted, pulled the double rectifier diodes and they were good. This is getting to be so much fun. Can't wait to find it a home. Thanks...

    Harman Kardon 930 tone board debacle

    I have a Harman Kardon 930 that had a stuck frozen bass pot outer knob that prevented me from removing the faceplate. Long story short; bass pot was ruined trying to remove the knob. Somehow, I successfully removed the board from the chassis to replace the pot. When I reassembled and...

    Sansui Eight FM Muting not working

    I did see VR 401 on the SM but it shows that trimmer is for FM Stereo Indicator adjustment. I didn't know that doubles as a muting adjust?

    Sansui Eight FM Muting not working

    My recent addition is a Sansui Eight receiver in untouched condition. I cleaned all the pushbutton switches as thoroughly as possible. Also cleaned the FM tuning capacitor per AK thread, cleaned all pots. FM stereo reception is decent with just a dipole wire attenna attached, with FM MUTING...
