    Marantz Repair advice needed

    You can also clean with de-oxit the preamp out main in jacks on the back of the unit. These are internally connected and can get dirty and cause channels to cut out. This happened on my 2325. You can use a patch cord to externally connect the preamp out to main in for testing to verify that this...

    Full range drivers- strengths and weaknesses?

    The best full range driver I have listen to is the Hartley 220 MSG. See this write up. http://www.stereophile.com/artdudleylistening/106listen/index.html They do suffer from narrow treble dispersion but they do sound good in the sweet spot.

    does anyone here like the yamaha "loudness" control?

    I like the variable loudness on my C-85 and Concept 16.5. I seem to never use more than 50% even at very low volume. I find some on/off loudness controls boost the bass to much and make the sound very muddy.

    Vintage amplifier "Speed" (slew rate)

    Just recalled back around 1977 I went to an HK amplifier square wave clinc with my Eico 3570(~1967 design)and my Marantz 2245. My old capacitor coupled Eico blew away all but the HK receivers at the clinic. The Eico had about 40 degrees tilt at 20Hz, the Marantz 2245 had so much tilt the output...

    Marantz 2325- dirty vol pot or bad relay?

    It may be dirty internal Pre-Amp to Main connections. Try using a patch cord to externally make this connection. This is the problem I had with my 2325.

It sounds very nice in that roll. I found a user manual for a AVC-30U that looks very similar to the AV-34. It says it...

    Hartley 301 drivers in Capri cabs?

    When I get a chance I will scan the data I have on the Hartley Capri's. They came in two versions, one with the 310 for $120 and one with the 220MS for $180. They both are 10 inch full range drivers. I think those are late 1950 or early 1960 prices. The 310 has a polymerised cone, molded cloth...

The Questra are a small 2way bookshelf with a 6.5inch woofer and one inch mylar dome tweeter. They seem to sound good. Any info...

    I picked up a Kenwood KR-8050 receiver w/red turbo button

    I believe the turbo button allows the output stages to run at a higher voltage to increase the power output up to 150 watts per channel. This should only be used with a single pair of 8 ohm speakers. Using 4 ohm speaker with the turbo button engaged may risk the output transistors. I think I...
