I have a very clean 60 wpc trade-in Jolida JD-502P power amplifier. It is rated 8/10. This power amp is an upgraded version of the 6550/KT88 tube amp as used in the JD-502BRC integrated amp. It adds Ultra Fast HEXFRED's in the power supply as well as custom Jolida capacitors and ceramic composition resistors. There are two 6550 tubes per channel to produce the great dynamics, detail and sonics that 6550/KT88's are famous for. The 502P has both XLR balanced inputs as well as single ended RCA inputs to work with any preamp. It uses custom wound Audio Transformers with a core of German grain oriented silicon steel. This is a 15th generation proprietary Jolida design. The secondary can be configured for a 4 ohm or 8 ohm speaker load. It uses gold plated RCA input jacks, audiophile grade carbon composite grid resistors, HEXFRED high speed soft recovery diodes and poly tin coupling capacitors. The EZ bias system uses LED's so no meter is required. This is a high quality tube amp that will run most loudspeakers. It offers great value at its $1100.0 retail. My amp is rated 8/10 for a small mark on the transformer cover. The face is perfect and the amp looks great as seen in the photos. We accept Visa, MasterCard & money orders.
