Bump for £280 delivered. Would also consider swap for valve phono stage.

The capacitors in the crossovers were checking out more or less within spec, but I thought it wise to replace the blue 80uF electrolytic. For the same price as a new NP electrolytic I got a Chinese film cap 82uF 100v (Bevenbi Axial MKP) which certainly looks more impressive, and initial...

So I've picked up a Krell KAV300i integrated with 150W to play with, so that should be fun, let's see how this American kit likes to party!

Agreed, it's a fun hobby, and cheaper than therapy

I remember one time a pair of omnidirectional Lowther enclosures I'd built, fairly ratty, but impressive with a pair of Quad IIs. I picked up an Audio Synthesis Desire power amp for £150 in a second hand shop, utter bargain, and hooked it up, expecting to be wowed. I remember the voice coil of...

I've received a Philips midrange unit from a seller in France, which saves posting one from North America. It's in place soldered in, the only issue is the red coloured basket, but beggars can't be choosers. I eased out the volume a little more this evening, and was impressed with the scale of...

Yeah, I just sold a Quad 405/1 a few weeks ago, typical!!

Here's the thing, getting that sort of current this side the pond just isn't easy or cheap. How about class D?

Well that;s the next question - what to run them with! I don't think my 300B SET is going to be happy...

Ooo, someone has spent a lot of money on capacitors there! Very nice. What you need to do is show a picture of a truly hideous speaker first (like a Hedlund horn in glossy pink), and then offer the Dahlquist as being a second option. Psychology...

Yes, I perused your thread on the way, and found it full of useful info, thanks!

You can understand why the designer wanted to put a cover on these, they are fugly brutes. But my word, even with a little Rotel 930AX do they sound good! To do list at present is - replace the pair of 80uF electrolytics when they arrive from China, pop in the right Philips midrange, then either...

They're alive!! A decent amount of music emanated from both speakers in appropriate quantities. I put on Radiohead Kid A - decent bass, mmhmm, positive noises... let's try some Kind of Blue - sounding good, but wait... Where's the tape hiss on the left speaker?? Re-test high frequency unit...

So, all good so far. Except... one duff midrange unit. Pants. Open circuit Philips DA5060/W8 unit on the right speaker, with no obvious easy repair. One ordered from France for £45, so not catastrophic. I checked all the other units and was briefly concerned that the piezos were open circuit...

Nice to see that there were some components underneath that thick layer of human and dog skin cells. After a bit of internet digging, I've decided to leave the majority of the caps in place, and just replace the sole 80uF NP electrolytic (the blue one), so I'll be waiting for a cheap Chinese...
