Uummm.. I could be mistaken but to my eyes the pic of the completed amp bottles shows half a 12AX7,two EL84's as finals, a filter cap and rectifier bottle..... If they are 6V6's the photo has some...

Very nice, almost professional looking... Just needs a "JohnH" logo in the corner...lol
Yeah, 15W EL84 tube amps to my ears are super nice cranked... plus you can play them wound up to 10 and...
Nice work... Looks awesome....
My only comment/observation - Looks to me that you have used Jaycar hookup wire everywhere. While it is easy to work with it is also NOT rated for many of the...
Yes, The switch in the link complies due the barrier between the two sets of spade terminals.
Technically your drawing can be correct. As was pointed out the primary 240vac winding needs to be one winding with a 120vac tap.... or two 120vac winding's that need a bridge between them.
A...
Yes, it it hard to know the state of play in any photo unless you are told so all you can do is make an observation...
That last pic looks fine in my books. Keep the blob soldering to a minimum...
Hey John,
Was admiring your handy work in the pic you posted, and found a point of concern. The tabs on your big electrolytic cap in the photo seem a bit to close for comfort to the chassis. It...
Thought I'd throw my 2 cents in here,
In my 45y playing in electronics it seems there is a definite trend to avoid the use of any material that can in its useful lifetime absorb moisture as an...
Thanks Ozz,... Full diagnosis is still pending but nephropathy in both the hands and feet is so disabling. Seems I'm spending more time in doctors offices and scan clinics than at home these days...
So, after illness and heartbreak I finally made it back into the shed to get sum building on...
I gave up on the burst cos I simply did not have the strength to do any serious sanding.... Can of...
A bit of searching and I was reminded that the speaker cabs at the entertainment venues at Expo 88 were predominately Concord TMS-3...
For a interesting read of Aussie PA and lighting history have...
Actually for the River Stage there were 23 Jands 920's per side.... 20 on the FOH each side (18kW + 18kW), and 3 more per side (2.7kW +2.7kW) on delayed stacks some 75m from the stage. (18 +18 + 2.7...
Grain fillers like Timbermate use water to reanimate to a consistency suitable for spreading so if your stain is water based the filler will come loose or adrift when you wipe on your stain, but the...
Your plan seems reasonable.
Just a word of caution. Some grain fillers will re animate when wet. As in you have done a wonderful job of grain filling and sanding for all of it to come adrift when...
How far you travel down the air brush rabbit hole is entirely dependent on the size of your wallet.
Once you have selected your air brush you will need a compressor that can keep up the air supply...
Yeah, hope you break a leg.... ;)
That's it ... My 15 seconds of fame has been and gone .... lol

Lol.... Nice score for $10.
Yeah Doc... I'm kinda keen on the Dirty Shirly board....
I just discovered this Melbourne based mob selling PCB's for guitar amps. Thought it worth giving them a shout despite not having bought from them yet. Will definitely consider on my next amp build
...
Oh wow, calling on detailed memory from 32y ago....
The Jands 920 was a brute at 450W RMS per channel into 8 ohms with 0.1% THD. It will do 4 ohms but not that well. Due analogue (non-switchmode)...
Recycling old electronics is much like trying to win the lottery. Sometimes you win, but often you don't.
If I'm building something I use new where I can. If I do use a recycled part I test it...
AU$250 incl postage for 2 transformers = BARGAIN.!!
I had a customer come in with a Lexicon Signature 284 that wanted it modified from USA 120VAC to Aussie 240VAC... Transformer had to be custom...
Yay !! ... Welcome to the club. The pain you go through now will wash away when your newly built amp barks at you for the first time... I know it did for me on my AC18W scratch amp build.
Yeah,...
