no longer for sale

DESCRIPTION 120 VAC North America. Audio Research CA-50 Integrated Amp Silver with Remote! Remote control was an extra cost option - Yes, this one DOES have the remote option. However, remote stopped working-may need a cleaning. Remote is sticky feeling as is typical of these. Note: amp works fine from working remote. All functions respond to my LS25 preamp remote. ***LINE STAGE ONLY NO PHONO*** New set of 4 EH 6922s. Matched set of Sovtek 6550s that tested good on my Hickok tester. Original manual. No original box but will be well packed. Amp is very holographic and musical timber is stunning. Much like a baby VT-100 MKII and build is similar. Has SUB output and can drive another preamp, power amp, or subwoofer. This amp is classic Audio Research - huge detailed spacious soundstage with tube depth of field. Not murky rather very fine nuances are conveyed. CONDITION Cosmetic: Excellent overall condition. 8/10. Front panel looks very nice. Function: Works very well. Remote stopped working but is included. PAYMENT Paypal (add 3%) or cash pickup. SHIPPING $75 shipping to USA Lower 48 states. $145 to AK, HI, PR, GU. $175 Canada. No international, please. Or local cash pickup is fine. From the Audio Research database: The CA50 is the first integrated power amplifier ever offered by Audio Research. It includes a 50-watt per channel all-vacuum-tube, push-pull Class AB power amplifier using 6922 twin triode tubes for input and driver stages, and 6550 power output tubes (one matched pair per channel). Constant-current source technology, distributed power supplies, and a dual-mono internal layout back to the main power transformer all contribute to the sonic power and finesse this model is capable of delivering. The volume control and input switching of the CA50 are via microprocessor- controlled relays, and a complete-function handheld IR remote control is standard. The ample chassis dimensions and functional internal layout of the CA50 eliminate the need for fan cooling, yet offer the covenience and easy installation of a single-chassis integrated unit. Up to 6 input sources including tape are accommodated. Output terminals are custom-machined, heavy-duty, gold-over-brass 5-way posts. In addition, a full-range, single-ended set of "Sub bass" outputs allow easy connection to a powered subwoofer or even to another power amplifier, perhaps for a remote system.
