The front panel of this slim, well-finished preamp features four toggle switches, one each for Off/On, Mono/Stereo, DIN 78/RIAA EQ, and Mute/Sound. The rear panel features one pair each of single-ended (RCA) inputs and balanced (XLR) outputs, and the circuit uses NOS 5784WB tubes. ...
They put in the circuit boards with the main board on top and add-on boards under it, so you have to lift up the whole thing to service anything and it makes it hard to adjust components and what not without the original service extension cables. They also used these "hybrid IC" thing...
"The push-pull, class-A/B INT-150 is rated to deliver 150Wpc (191Wpc at clipping), and has a high-quality volume control and five inputs: two XLR/RCA and three RCA-only. It uses Pass's Super-Symmetry Circuit, previously featured in all X-series models, to naturally eliminate distort...
However, if the pads are the same size as the clip lands then the solder will tend to bulge out like the filling in a sandwich when you squeeze it. If you add alignment holes in the PCB, even if you don't use them for mechanical fixings, you could afford to make ...
The revived 75Wpc MC275, preserves the look of the original while adding modern innovations. Chimneys are used to cool the tubes by convection, and three circuit boards have been replaced by a single board on which are mounted all components, tube sockets, and power-supply parts. ST: "I ...
or upgrade paths for USB connectivity. Apart from a small circuit board containing the bipolar timer and relays, the Phono Integrated is hand-wired, point to point, with neatly made solder joins and Bakelite terminal strips. AD liked the Croft's dual-mono volume controls, SM not so much. ...
(The Duo's two halves are even shipped in separate cartons.) Construction details include steel casework and thick circuit boards, the latter to prevent unwanted capacitance, and loading and gain are adjustable by means of internal jumpers. Input and output connectors are limited to RCA jacks, ...
circuit boards, and upgrades of various parts. Measuring 16" W by 8.25" H by 20.375" D, weighing 81 lbs, and with 14 tubes total (all of which must be installed and adjusted by the user), the ML2.2s require careful setup. Though it lacked the Shindo Haut-Brion's knack for ...
