The Phono has an important-looking «Interference Switch» which is just a resistor, to stop RF which we’re getting on the B+O as it’s piled on others. It seems to be the biggest & most wanted one. You could easily put 30 hours & £300 in new paets to do this right, if you have the skill & patience. Стал счастливым владельцем реса НК AVR-445. До этого был Денон 1507. Акустика B&W DM602 (фронт и тыл). Источник — CD Пио PD S504, ДВД Пио 610 и медиаплеер BBK-070. Шланги не крутые, но достаточно хороши.
The ugly cabinet we got our silver-grease Garrard 301 & the Dynaco in shows why many are abandoned. The Phono board appears right next to the heatsink with no shielding. How strange. 1973-75 55w RMS. One nice site lets us board gazers look inside. Only 18w though & a bit random looking inside shows an ebay one in Mar 2015. Phono is an IC if it shows 2 transistors inside, why not just build it on a board? Скорее всего, что не удается отодвинуть их от стены на достаточное растояние. This is a 50w amp from as early as 1969 by the brochure date if only in the 1972 HFYB, or it’s 200w if you believe the naughty music power hype, soon made illegal.
The Quad II power amps are something special though the 1.4v they need from a preamp is awkward & you can’t change the design as we had a deeper look at the circuit. Out of the boxHaving seen the glossy catalog sheets, I was unprepared for the HK 990’s weight and solidity. My sample had been handled by other reviewers, and its volume knob had come off in the carton. Our opinion is they are not worth buying unless you really want to totally rebuild it & for that effort you’d get a decent early valve amp, so if you can take the challenge we’d recommend it on that basis if the exterior & fascia was tidy.
