    Marantz Transistor/Diode/Trimmer Sub Guide

    Hello All. I downloaded the substitution guide but I don't see a substitution for the 2SC496 (H714/H715). This transistor is used on the P700 power amp in the Marantz 2325. What substitution is currently being used? Thank You O. Frank

    Marantz 2325 Transistor Substitutions.

    Hello Everyone, I need some help from all the Marantz guru’s. I have read in another post that the possible cause to an intermittent loud popping in the 2325 power amp might be the H706 - 2SA818 and H707 - 2SC1628 transistors. I see that the recommended replacement transistors are KSA1381for...

    Marantz 2325 Amp Board Trouble

    Have you replaced H718 and H719? They set the bias level for the driver stage. If they have not been changed, you can check the bias on H706 and H707.

    Remote speakers

    Marantz amplifiers are very capable of driving a 4 ohm load. I’ve been using 2 sets of speakers (EPI 100s and JBL4312s) for more years than I can remember. Have never had an issue.

    Marantz 2325 blowing fuse FR01

    First think I would do is unplug the main amplifiers. If it stops blowing fuses then it's one of the main amps. if it's still blowing fuses then it maybe the power supply, or main filter caps, or one of the main rectifiers.

    Marantz 2325 restoration

    I concur with Steve. The leestereo is the standard but there are other threads. When I did my 2325 restoration I researched all of them and put together a plan to tackle it board by board. Good luck. Again, as Steve said, test after you complete each board.

    Rookie on a 2325

    The DC offset/bias seem good enough to allow for the relay to work. Therefore, with no relay click, I'd start with the p800 - power supply board. There may be a bad component in the speaker protection circuitry.

    Smoked 2330 - Both Channels Crispy

    Yes, you can use 1/2 watt in place of the 1/4 watt resistors. Just beware that they are a little larger and space may, in some cases be an issue. Also consider beefing up the power resistors on the board. Again beware of the size. 'O'

    Marantz 2270 VS JVC AX-Z1010TN

    Personally I would never give up a Marantz 2270 unless I was trading for a Mcintosh.

    Marantz 2245 left channel went out while listening. Repair advice?

    When cleaning you controls, don't forget to clean the pre-amp out and main amp in connections. And as others posts stated, is only on phono or other sources too?

    Marantz 2325 Dial Pointer Protector

    Thank you for directing me to the right place.

    I know I’m a bit late to the show, but The 730 has a modular main amp. The connections often get oxidized. Try cleaning them with Deoxit. Also, clean the switches and controls with Deoxit.

    Marantz 2325 Dial Pointer Protector

    I’m looking for a dial pointer protector for my Marantz 2325. I bought this receiver on eBay in 1998 or 99. It did not have it when I got it. If someone has one they would like to sell please let me know. In the service manual it’s Ref# 1431. Thank You O. Frank
