    KLH model 30 component compatibility with Model 6 (not the earliest version)?

    I have a set of the 30's. One difference is it has an RCA speaker connector in the back and I had to upgrade to banana's. They were sold with systems, so they came with the easy hook up above. Warehouse Sound Company used to sell them in one of their systems: Marantz 1060 KLH 30's and either...

    Help with resistor band ID

    Does anyone know what the 5th black band means on this resistor? From what I can tell they are Corning Electrosil 1/4W 2% TR4 from the RL07 series. The thing is every other time I've seen Corning RL07s they have had a white 5th band, which I think just means it has military solderable leads...

    Marantz 2385 PreAmp-Tone Board (PE00) Diagnose/Repair

    I would remove and clean all these circled solder areas. Make sure all is well, add a jumper wire if needed. Then resolder and check.

    Marantz amp board trimmers? Is there an error?

    Is that unit a Euro version? I see the fuse panel along side the heatsink/amp board. I thought it was usually on the bottom?

    2270 phono issue?

    I would make sure the 1229 is checked complete. *check all wire connections bottom of deck. *Yes Dual muting switch is a known problem. *Many are now using 2SC1815 transistors to replace the 2SC458's on the phono board per the service bulletin. (may stop hum/motor boating) *In the past 1845's...

    Baxandall Diode and Vbe By-pass 2015 & 2230

    I would still recommend keeping stock. (see post #3) Just my two cents. Makes for better proven long term reliability and future service work if required.

    Baxandall Diode and Vbe By-pass 2015 & 2230

    Got it! Did you replace any onboard transistors on that unit? That at times can put the trimmer out of range. (Actually usually)

    Baxandall Diode and Vbe By-pass 2015 & 2230

    I will add another caveat: If your amplifier board/boards transistors or outputs have been changed this adds it's own twist to the situation. The trimmer will probably be out of range, and adding the mods will/can make matters worse.

    Thanks Ben, I first saw this for a Sansui 2000X by @ConradH: https://conradhoffman.com/Sansui2000x_mods.htm Just a little worried about first time rebuilders adding this into the mix of a rebuild that sometimes may complicate the process. Just make sure that your receiver is able to be set...

    2230 - P750 Board - C760 Replacement

    Hi, That cap is fine. Caps under 5uf will measure like that. I have measured that same value film from Marantz and it is usually 15-16 ohms.

    Great job staying with it! Post #4 and post #6 by @petehall347 and @rBuckner mention this was probably the problem.

    Marantz 2230 "Leaning tower of CAPZILLA." Show us your before and after large cap installs!

    I love bringing back each Marantz I work on to proper fit/function. The build quality on the 2230 is excellent, to get this today you would spend big $$$!!! Love the way these receivers bounce back! Here is the before and after large cap install. (The power cap was also "hot glued" in place.)...
