Counterpoint SA-20 Hybrid Power Amplifier, 220 Watts Picture and Description:
Counterpoint SA-20 Hybrid Power Amp. 220 watts per channel, can be bridged for 600watt mono operation. Unit uses tubes in the front end and mosfets for the output stage. Unit uses 4 6DJ8 tubes in the audio section, one 6DJ8 for phase when unit is bridged and one 6CA4 rectifier. All tubes have been tested on my EICO 625 tube tester, all tubes read greater than 900 on the meter, max being 1000. Basically all tubes are like new. I have never seen a tube read greater ten 950 on my tester. Unit works and sounds great. I did the following upgrades to the unit, replaced the original RCA jacks with WBT jacks, added a switch for chassis ground, added a IEC power plug so a detachable power cord could be used, I never like the way counterpoint ran the AC main right under the audio pc board. The plug I put on mounts right under the power transformer this way the AC cord is not right under the audio board. I had to add spacers to the feet to accommodate the plug, see photo. I also added a wall between the transformer and the audio section of the unit with additional heat sinks for the rectifiers. I have the original bow and manual. I will double box the unit. The front face plate was swaped with on from a SA-220 amp, a friend of mine had a SA-220 the he wanted to mount in a rack setup, the SA-220 faceplate does not have holes for rack mounting and the SA-20 does so we swapped faceplates. Unit has not been used much over the last few years, I upgraded to a rowland amp. I have the unit running right now, sounds great, I hate to sell it but I just cant justify holding on to it any longer.
