    Crossover/L-pad help needed!!!

    I picked up a pair of Utah speakers which I believe are probably A-100s but I'm not sure since pics and specs are few and far between online for these. Anyway, it uses a horn tweeter, a small compression driver, and a 12 inch woofer as depicted, in an acoustic suspension cabinet. Crossover...

    AR2-AX restoration questions (and documentation)

    I've surfed through many AR restoration threads and have a handful of questions that I haven't seen addressed elsewhere. First up is where I can source good replacement grille cloth. The cloth on mine are pretty dirty, and the cloth is pretty delicate. One of the frames in busted, too. I'm...

    Yet another butchered 250

    Alright, so some of you guys probably remember my last thread on the 250M that was toasted, that one went smoothly and was a great learning experience all round. Anyway, I have a new challenger now... A Marantz 250 that's been very much molested. Right now I am trying to assess the damages, it...

    JBL L100 Restoration

    Hey Guys - I'm planning on restoring my old JBL L100's that my father gave me long ago, but wife put me on a budget. I wish I had taken better care of them when younger as they are in rough shape and been through a lot. I'll definitely have to re-cone the woofers and refinish cabinets, but...

    Cleaning a Thorens turntable mat

    I was going to clean my thorens turntable may but for some reason got cold feet when I went to vinyl nirvana and saw Dave claim that there is a ‘special cleaner’ he used to clean the mats. I was thinking about using dish soap and warm water. Would this be the equivalent of Dave’s ‘special...

    Yamaha CR-2040 Shorted During DC/Bias/Voltage Adjustment

    Well, I'm pretty new to this and probably have no business digging into the likes of a CR-2040, but this is what I've found to pass the time and I'm enjoying every second of it. I picked this CR-2040 up for $200 knowing it was cosmetically great aside from being dirty and there was no sound out...

    My Fisher 400 restoration and modification project

    I picked up this Model 400 locally last summer with the intention of restoring it for use in our living room. I love my other Fisher gear, and my fiancee likes the glow from these big Fisher receivers. I won't say no if she endorses any audio purchase! Other projects have kept me busy, but I...

    Kenwood KA-2500 "spirited" offset

    Hello all! I picked up a Kenwood KA-2500 at an auction a couple of months ago, and have been working to restore it. Unfortunately I've hit a bit of a roadblock. Upon initial testing I found that it had a light hum and a horrific +20VDC offset on both channels that gradually falls to a much...

    Kenwood KR-6600 restoration etc.

    I have been working on this Kenwood a lot of this week. A friend sold it to me cheap, as it was stuck in protect mode...

    AM not working after recapping power supply

    I recapped the power supply of my MCS 3223 and it was somewhat successful, I made the hum go and it's sounding a lot better now. However, I believe that in the process I might've moved or fried something that stopped the AM signal from working. What should I look for and where should I look if I...
