    Replacing fixed RCA cables

    I have had a Technics SL-2000 for about 15 years. I picked it up for free because the previous user busted the RCA cables. The first thing I did upon picking it up was to remove the bottom of the turntable and use some electrical tape and some twisting to attach the new RCA cable to the fixed...

    I got Dimensia...

    I found a nice pair of RCA Dimensia SPK-400T's at a yard sale yesterday. I very quickly tried them out and all drivers work. The woofers need to be refoamed, but I can't find the proper kit anywhere. These have 12" woofers and all I can find are the kits for the SPK500 which have 10" woofers...

    Will this DIY improves your sound??

    So here is the big question: if you cut short your RCA cable, connect it with a female RCA then use a much better ($$) RCA to the amp, will the sound quality be better just as much as using the whole $$ RCA or at least very close? I have an Audio Technica LP120 turntable, love it a lot. Two big...

    New build: how to install RCA with isolation washers?

    I have some switchcraft RCA connectors (3501FRX), and I also have the manufacturer recommended isolation washers (s1028 and s1029). Does anyone know what order/how to install these so they are isolated? I can't seem to find a drawing or anything. I just don't know where to put the isolation...

    RCA 70-C1 Transcription Turntable

    Recently became the owner of this by way of a trade with @musiqlovr. All I can say is that it was worth the 14 hour round trip. I've been incredibly interested in broadcast turntables for a while now, but never dreamed of owning something like this. Since getting it home a few weeks ago, I've...

    Dual CS 1257 RCA cable replacement

    I have a Dual CS 1257 that needs a total RCA cable replacement, the wires were clipped very short. I've spliced in a new one for now, works fine. But I've noticed the older copper is much thicker on the original wire. Also, it has those spade push connectors. Question, I see an original Dual 505...

    Using both DIN and RCA on one tape input

    Hi guys, Quick question: Is there any harm in using both the DIN connection and the RCA ones on a single tape input, for two different input devices? Exemple: I'm running out of inputs on my Kenwood KA-6100 so I put my reel to reel on the RCAs of "tape B" and my cassette deck on the DIN input...

The model 5000 not only needed new belts, but I had to take the whole transport mechanism apart to clean off the harded old grease. Eventually I got...

    Complete newbie: RCA VMP 38

    Hi all. I admittedly have no clue what I am doing. I bought this RCA VMP 38 online for $30. Figured it was worth a risk if it was junk. How do I figure out the cartridge. Am I missing a piece because it won’t stay in?

    I have an RCA RS-178 in excellent condition. My friend that gave it to me told me it’s in excellent working condition (and I trust him very much). I just don’t understand how to get this working with my turntable. I can upload pictures or whatever is necessary.
