AKP only use my 4500 for 3 years while the amp was made 25 years ago.

He had quite a little down but nothing too serious. I bought a store PA who uses their rental fleet. The seller told me he had been recovered in a nightclub after a renovation.

This behemoth of steel and copper has a perfect sound in my ear, the 2X225W are more than this. I use it with a pair of homemade HP SP25PA consist of two (125W rms 8H 97dB) and an MHD 152 (75W RMS 105dB 8H). This all gives me a great satisfaction. The lack of serious (all relative) at HP is simply offset by a subwoofer amplifier, also homemade.

I also use it in Hi-Fi but is the classic trasfo proved too noisy for quiet listening.
For the sound I made with rac bais power and an equalizer. On the side I also put two ventilos end it brings a bit of fresh air.

What I like least
_ Weight
_ Noisy transformer

What I like most
_ Sound quality
_ In the real 2X125W 8H, 2X225W in 4H and 8H 450W in bridged mode.
_ Passive dissipation
_ Chosen to design the RCA or XLR Jack (but the input is not balanced)
_ Double the meter (yes it's a little jacky but it's nice graduation Watt)
_the black brushed aluminum front panel
