Im beginning to like the old Rogers amplifiers. I have a PX4 push pull with Partridge transformers which I have just rebuilt all new valves. It is supprisingly good. Next I would like a PX25 based amp same transformers might this also be a Rogers? Any one interested in the PX4 I will do the photo bit, its teh sound that is so good must be 15w redid the bass attenuator now there is a more genereous bass response R50s of course. Graham saunders

There is a pre amp that goes with this, I will have to take some photos if anyone wants to se it.

Hi,

You know how things just stick in your mind for days, well if you want to part with this and the preamp please contact me at. I have a Rogers px4 amp with Partridge transformers which I have just rebuilt and it is good.

Yours would no doubt be even better, many thanks, would like to see preamp pictures if possible.

One 1960's Practical Wireless cabinet used poured concrete panels!
This is all pre "book shelf" reproducers or active units, of course.
A BBC Transmission Speaker [or equivalent] might be an alternative.
Seems to be a lot of info on the net. Dave W

It seems I have acquired a A&R 12 inch coaxial speaker (made in the UK, date unknown) c/w crossover. No enclosure.
This will be used with my Williamson amp.
The idea of using concrete or brick to build an enclosure certainly appeals to me but I think I'd like to start with wood. Anyone have pictures or ideas for such an enclosure out of wood?
Input would be appreciated.

Hi Septimus, try googling for speaker enclosures and you should finf details of some of the 50's designs for home constructors. Many of the speaker manufacturers produced cabinet designs to go with their speakers.
