Description

Sponsored post - log in to remove this ad.

Made with Cherry wood trim and cherry wood remote controller. Pictures don't do it justice - must be seen to appreciate it's beauty.
Bought it many years ago as a collectors item. Played less than 10 hours to checkout and adjust tube bias. Been boxed ever since. Have original invoice as proof for purchase verification



SPECIFICATIONS for amplifier JJ 828 - integrated amplifier with remote control

70 Watts output power per channel using high quality components
- Five RCA inputs switched by signal relays
- Tape output RCA and 4, 8 Ohm output
- Dual independent power supply for each channel
- Ultra linear circuitry with KT 88 tube
- High operational current of KT 88 (75mA)
- KT88 cathodes feedback (CFB) via C-core type output transformers

the ECC 82 tubes are used as a phase inverter 1st stage while the ECC 99 tubes are used as a driver for the KT 88's. The ECC99 is a tube specifically developed by JJ Electronics for application as a unique linear driver for high power tubes

There are two feedback loops in this design: one is a global feedback from Output Transformer (- 6 dB) and the second is from the secondary cathode winding of the Output Transformer (5 dB).
The cathode winding feedback was what Mackintosh was famous for in all it's amps.

Output transformer is a C-core type which is superior to the normal E-I type
Each output transformer has four primary, four bifilar secondary and two feedback cathode windings.
