ILP Amplifier Modules

qazkq8v · 29th April 2006, 02:05 AM

There is a company out of the UK named ILP Electronics. It makes a range of power amp modules: basically the entire amp circuit is embedded in some vitreous material bonded to a heat sink. Most of the modules have 5 connections: ground, Vcc+, Vcc-, in, out; though some integrate the PSU less the transformer as well.

Has anyone used these? Are they any good?

Hi qazkq8v,
I am very familiar with the ones I sold in the late 70's and early 80's. There were what you describe.

They sounded good back then. They blew up easily if abused at all. They could be destroyed instantly from poor grounding when wiring them up. I built a stereo amp that worked well for years using a pair of HY120's (60W). The guy I sold it too blew it up. I don't think it took much.

I built an ILP power amp in 1988. I don't recall the model number but I remeber the specification called for +/-40 to 57volts rails (or similar). I drove it with +/-60 and the two modules died within days of use. I don't think they were engineered for "good times". As I recall I purchased the 2 modules at Active components on Lombard Street and they were very expensive.

I thought I saw some recently in a surplus store, wasn't ILP connected to Plitron somehow or am I making that up?

I have some ILP brand toroidals, very nice transformers. Maybe that's the connection?

Blast from the past.

They did sell toroids (I have one from around 1980), now only made to order by the look of it.

I used them for disco work in the seventies. !00% reliable.
