single mono HH - H&H TPA 25-D BBC - Rogers LS3/5A spec - studio monitor amp / Monoblock

Single rack mountable 1970's TPA 25-D BBC spec HH Amplifier

Amazing condition and fully functional.

These were made to BBC specifications under license by HH

You can’t buy a finer studio monitor amp, these were designed to drive the BBC designed LS3/5A speakers made by Rogers, Chartwell etc

You can of course use these to drive any studio or hifi monitor

This is a 75w amp and can drive either a 4 ohm, 8ohm or 16 ohm speaker load

These have voltage selectors so you can use them anywhere in the world, the sale includes the original power lead

What I love about BBC kit is that they had such a large budget/were such a large corporation with a big budget back in the day they could afford to build things/commison stuff to the highest specifications possible, BBC broadcast spec kit was designed to be driven hard and function in any environment. 

Their is nothing in modern production that can touch these in terms of build quality / sonic quality

Anything else just ask
