Hi Andy, it's ready to run but we didn't get the chance to do it due to my commitments on other matter today. The first trial will be run next week, I'll keep you posted.
Sweet!

Should be a fun and exciting day.

Looking forward to ya' write up  8)

It LIVES!  ;D

Sorry to disappoint anyone who is expecting a decent looking tube amp. I know I still have a looooong way to go...

Thanks to Mr. Garland, I am one step closer to starting my dream journey :)

I'll call my amp Gargoyle 50 from now on :D

Thanks Ian. It will look better, rest assured ;) But the most important thing is, how it sounds and to me I can hear huge potential of this amp, Steve really knows his stuff :)

Hay, it really does look fine to me, mine's finished and that looks near as good as it :)

Looks fine to me also, because it is the sound that matters *thumbs up*

Hi James, the plan is to get my boxes in June, I'll be in touch when I come up there :)

Thanks rab. Are you going to build one soon for your horn system? :)

Hi Andy,

I started very slow, didn't have the cash to burn so I was slowly saving up and buying the parts little by litle...and man how I enjoyed the process of getting the right parts at a bargain price, ask Steve about my pair of Axiom 80  ;D

My stereo hobby has consumed more of my life too and I regret nothing, in fact I feel alive when I go up to Steve's (5 hours return trip that is) or listen to my system after a boring week of work.

Things will come together Andy and I am sure you know this too :)

Cheers,
William

Hi William,

How is your Gargoyle 50 amp project going?

My system is at the point where it only needs a couple of good quality watts to run the drivers, so have been toying with the idea of building something similar myself.

Hi Tuyen,

I haven't had time to complete the project yet, was very busy with work until last month.

The amp was running fine but I've burnt out two type 50 globes because the filament was too hot so I need to change the filament transformers. I will update this thread when I do that.

Running your horns with SET amps sounds like a good idea but you might want to ask around because last time Brian had one built for his horns but I heard he didn't use it because it's too much for his horns and the sound became bloated.

Cheers,
William

Thanks William.  Look forward to some updates later on when you make further progress.

I've ran a few SET amps on my system already (300B and 6L6).  Just now wanting to go a lower more 'pure' 45/46/50 SET :)

Speaking of killer amps,  look at this pair of mono blocks, owned by Peter Ashton.  They run huge STC 212e valves and output about 70 watts single ended class A. When he switches them on the lights in his suburb dim. You can get an idea of how big the 212s valves are by looking at the 5U4G rectifiers nearby.

STC 212c...........Niiiiiiiiiiiiiiiiiice valve of the 'adult size' but valve amps on the carpet :o

70 w of pure class A is really cooking and should drive anything with some authority, my poor old 211's pale into wimps in comparison despite having a B+ >1000v volt rail, they get really hot too so supports and ventilation require some thought.  Where is the circuit design for that amp and who built the amps?  I would love to be able to clap ears on them at some point as it could be a step up from the Ongaku 'sound' or may be similar but with more drive and 'balls'.

Steve, the output from these amps is only 40 watts class A.  The HT voltage is 1250 volts.  14 volts dc at 6 amps on the heaters.
