Thanks Phil, me too. It's been a bit of an interesting one.
I don't have any "full range" speakers to test it on at the moment as I'm using active crossovers, but above 415Hz it sounds nice!

Well, all being well, I now (show last weekend) have tested the packing boxes to put the OB's in and have a van booked for Owston so we should be able to try your amp with them which I look forward to.

That's great Nick, looking forward to it too. We can all crowd round them to hear the mighty 2W .

Now I've just remembered I didn't reconnect the driver grid leak resistors...
Well done on the fault finding though, rewarding innits?

If ever the usage of that word were apt it's now .
But yes, very satisfying to have sorted it (without any apparent damage except for the IEC input).

Hooorah! I'm just catching up but hoorah again. Dropping in and out of WiFi somewhere just east of Windermere the real world seems a long way away.
ONWARDS!

Heheheh, I remember working with you and NickG on your 3 stage amp on the floor at Owston, low OP on one channel, the spare OPTX secondaries were neatly bunched up but unexpectedly contacting the earthed bracketry that held the LS terminals. "That'd do it!" was the collective joyous cry
Funny how some faults stick in your brain innits?

Yeah that sticks in my mind too - it went through it again this weekend when I was thinking about what the problem might be lol. But this time I've used plywood to mount the binding posts now ally so that was easy to rule out!

But the bit I remember most is when you announced to the room that "Simon's done a poo poo".

I always think it best not time add up component parts. Especially if an "audit" is being carried out
#133 Re: 45 SET
Yep, but they are all used, so a lot cheaper now.simon wrote: Wed Oct 12, 2022 8:50 pm I always think it best not time add up component parts. Especially if an "audit" is being carried out

Yep. And TBF there's an awful lot of recycling happened over the last 15+ years. There's a fair bit of that amp in the 45 amp now.
I wince now when I see how much more some things cost. Like little 5751s at £80 a pop. Makes me realise how little I've bought over recent years.

Yes Simon, vt4c’s have rocketed. Even gm70’s and gk71’s, though not on the same scale as Western valves, since Russian conflict have doubled..
I cant get a figure on V1505’s any longer as ebay searches for the various designations come up blank. When I and Darren first searched them ebay searches at least knew what we were talking about. now ebay is clueless what Im searching. But with new Chinese production costing $1200 Western manufactured versions certainly worth a lot more than the prices we both paid back then.
At one time military ECC82’s cost me £5 from Derek Rocco, relative price today multiples of that.
But, there is a risk the bottom will fall out of the market. I dont really care, when Im all burned up at crem nothing of such trivia will matter.
