Tone Control Mods on a Vintage, Tube-Era Sansui Receiver
I'm using LTSpice circuit modeling software to modify the existing tone controls, remove the high and low filters, and design a bypass of the tone controls.

Problem Solved! Vintage Receiver Malfunction Fixed!
มุมมอง 3912 หลายเดือนก่อน
A Yamaha CR-620 looked fine without a load connected to the speaker terminals, but with a load, half of the waveform was missing! A bad resistor between the "pull-side" driver emitter and output base was the problem. Heat damage and increased the resistor's value by more than two orders of magnitude. With no load, almost no current passed through the resistor, so voltages were normal. With a lo...

Do Cables Matter? Testing! Differences Detected!
มุมมอง 2.1K4 หลายเดือนก่อน
A/B testing of flimsy, cheap cable and a $20 cable connecting CD player and preamp. I listen for the differences and look at the differences after loading the recordings into Audacity. I select a few small samples, less than one second long, and compare the power vs. frequency spectra.
Preamp Mod For Moving Coil Cartridge!
มุมมอง 8914 หลายเดือนก่อน
The Rega Apheta requires phono preamp input impedance of 100 ohms, but my preamp's moving coil stage has an input impedance of 22 ohms, so I replaced the resistors in the voltage divider at the input.

    Our first 'real' turntable was/is a Dual 1019 in a flip-top wooden case case. I recently purchased its twin and looking forward to getting it back in use. DW has a huge collection of lawn-sale 78's she's anxious to hear, We got our first B&O turntable when the 4004 came out in 1978. The only 'repairs' it’s needed? A replacement drive belt for the tonearm in 1998. The MavGyver fix was the entrance end of a condom, (still gripping today). The other was a drive belt for the platter, OEM was/is available. I've used a Soundsmith cartridge since 1985. SMMC20L+. I recently bought another 4004 (A Soundsmith 'The Voice' will be used. As you can tell, I love the 4004 and Soundsmith, but a disclaimer is needed, I'm no expert, just a loose association of my own thoughts. “It sounds like bacon smells”, Bonnie describing her vintage 1965 Stratocaster Bob

    I have a Sonos surround sound system setup in my den for music and video entertainment. Have Sonos speakers through out the house. The problem is I grew up when these receivers/systems were king. I always get nostalgic when watching these videos about vintage receivers and find myself wanting to get one. But, then I have to ask myself other than the beautiful dial face and exquisite looks a vintage receiver would bring to my den would it be better than what I already have. I just don't know. First world problem.

    I glad that you mentioned 7591 power amplifier output tubes. Both of my tube amplifiers use four of the 7591 tubes in their output stages (McIntosh MC225 power and The Fisher x202B integrated). I love the sound these two amplifiers make. Just beautiful! Neither amplifier will play loud but they will provide palpable bass response at normal 60-70 db listening levels. I use a Vinnie Rossi LIO as a preamp and vintage JBL L100s as loudspeakers.

    Nice talk on records and their meaning to you. I’m sure many people have a similar relationship to their music collection. Alongside the record care tips presented here; I think it is important to keep records in a stable atmospheric environment having constant temperature and normal humidity. A moist environment will cause musty smells on record jackets. Mold will grow on the surface of vinyl records kept in wet atmospheres. I do keep my records in plastic cover sleeves. But - I am concerned that the plastic sleeves may trap moisture in contact with records and alow mold to grow. It might be a good idea to take a close look at cartridge styli under a microscope every now and then checking for wear and/or damage. Joe Collins has some very good talks on his TH-cam channel with graphic picture examples of various stylus shapes. Joe explains how certain stylus shapes are best and safest for certain types of records. For example; styrene 45s should be played with elliptical shape styli not fine line stylus shapes.

    There is a great film called Desperate Man Blues (2003) about the 78 rpm record enthusiast, Joe Bussard. Joe played his records with at a big long tone arm Technics turntable with a slider for adjusting pitch (speed) on the fly. Joe stated that many records were not recorded/manufactured at the specified speed. He knew his collection of nearly 10,000 records so well that he could adjust the pitch (speed) of record being played as needed when listening. There are so many variables that could impact the pitch of recordings along the recording, mixing, manufacturing and playback chain that I personally don’t worry too much about one or two percent speed irregularities of my turntables. Both of my tables have pitch (speed) control sliders that I have never used. They might come in handy for certain recordings if only my ears and brain could notice an issue with pitch. Thank you for bringing this subject to the forefront and thus quality presentation.

    Great video! I own a 70's Rosita T6500 set with a Dual 1214 full automatic record player. I restored the set over a 5 month period. I really enjoy putting on a record on a lazy sunday afternoon and listen to some old jazz or blues. So it's vintage for me.

    I grew up listening to my dad's Garrard semi-manual, LaFayette amp and tuner and EMI speakers. My first records were 'Sing along with the Chipmunks' and 'Christmas with the Chipmunks', which I still have, complete with crayon scribble on the sleeves. I still have the Technics SLD-202, and the Onkyo TA-630D cassette deck that I bought in college (late 70s). They survived 9 Navy/personal moves and I just finished replacing belts and a few bulbs in the tape deck. Phonograph's been fine all along. I still have 200+ records I've acquired over the years, and a bunch of my dad's, all in near perfect condition!

    I made a great many "mixed tapes" from this deck when I was 16. My dad gave this one away when he upgraded to a CT-F750. I really didn't understand tape decks back then. There was no "Dummies" book for these things, only audio magazine articles where they assumed you knew what the hell they were talking about. If I only knew then what I know now.
