These are intriguing, assuming the description is accurate. I rather like a bit of AI:
Have you got silver ICs though?
Ideal summer amp for the horn brigade.

The pointy bits on the ends are sort of silvery.
The other bits are more rubbery and/or plasticy.
Itās cryoed silver or youāre wasting your time 
Perhaps I could rub it with an ice pop?
There appears to be a big hole where the choke should be.
I had a pair of dodgy AI 6B4G monos. They were fantastic, and I regret selling them. Although I think mine were better than those, and I sold them for a fraction of that price.

Most of those didnāt have a choke in the psu. These items (maybe 30-40 pairs) were built before the stereo FAA came out. They used the AI Series 300 (Hinchley) mains transformer and the Savage PushPull output transformer from the S800 Mk1 power amp. An extra small internal transformer rectified & smoothed produced a fixed bias supply (-45v) if memory serves. AC heating on the o/p valves (with a humbucker pot) means thereāll always be a little residual hum while pretty high input sensitivity means that an active line stage may have too much gain to be user friendly with these. A passive volume control or an autoformer might be the best bet.

Not eBay but worth a look. I did consider buying it myself, but decided the UK one is enough Ltdās in the system!
I couldnāt resist. 
Nice one.
What did you get it for - I was thinking of a cheeky offer of Ā£1k.
Would love to try it with my WLMās if you ever have it sitting around unused.
Ā£1k plus postage. You are welcome to borrow it.
Good buy. Be interested to try with finos
Yes, do let is know Bob. There are not too many of those kicking around. 50W/ch?
It puts out about half a watt in class A and then upto about 30 watts in a/b.
There is a newer version called the Model 3 - one on audiomarkt which I made some enquiries on before I bought the FirstWatt.
If anyone fancies having a go on Guys Nob hereās your chance
Meh. The 747 is better. Has a choke in the psu, accurate RIAA and is in a box tall enough that the rectifier can be used on the pcb as intended. 
(Iām more bemused by just how many different takes there have been on Graham Allenās original casework design for AI which dates back to about 1990. Many companies have borrowed the pillars in each corner style.)
Not a problem. Bob
