I bought this amp in 1976 to replace a Braun CSV-300 (my first amp) which was a bit "short" power for Ditton 66.
Qu'alléchantes well, we can never say enough that the measures do not replace electronic listening, and they can be manipulated to improve the balance: An example, food was too narrow, and if the amp provided two x 50 w / 8 ohms at 1000 Hz, it only gave more than 2 x 35/8 ohms 40 hz. Measure reported in the data sheet was made one channel power. That said, it worked well but was neither worse nor better than many amp time. A 2490 F anyway. Amp "BOAF ...". I kept three years, a little disappointed but the bank account was a bit underpowered to replace before.
