I think you might be right Phatt, I think I was just feeling and thinking like I did back in the 70's.
If I called you an old fart I would be insulting myself too. But who cares how old we are.
Life is like a long train journey, the smart ones sit back and enjoy the view, the rest worry about getting to the destination on time.

I wonder if most upcoming groups in the future will use mainly SS amps like these ?
Why would a young person spend 10x that amount for a tube amp, I think the music scene will change very soon.
If a young band builds up their style and sound with SS amps why would they ever to to tubes ? It would not sound right to them.

Here are the last files, made with KiCad 6.0.2 , great free program for making up PCB's
Also positioned the pots on the PCB to correct spacing but did not make a PCB up.
Also a scan of the track side of the PCB (Mirrored to help trace components on top)
The scan is fuzzy because it was lifted off the scanner by the heat-sink bracket.

I might keep this amp, in original condition purely to conserve it as an original, if I want to mod it I can always make a copy.
(Apart from the Electrolytic caps, changed them when I had the PCB out)
If anyone can help me with the Reverb Tank identification, or new equivalent type, then please do.
Also if someone knows what D14 might be, please guess away.

Schematic completed, I don't know if I should post it under "Schematics and Layouts" as well ?
I can't work out what D14 is, the one that is mounted in the heatsink, see above pics.
I have no idea what the Reverb Tank is, it looks like the same shape as the old Folded Line ones.
The Out coil has a Red bobbin. the In coil has a Blue bobbin, resistance DC on schematic.
The only writing on the reverb tank is "26  87  278" on one side. (And Input & Output on other side)
If someone can identify the tank, or a modern replacement, then please post it here thanks.

The Schematic is traced by me and I can't guarantee it is 100% correct, but I think it is.

More Pics

Pictures of the amp when I picked it up, it works perfectly, no problems.

G'day
I love making up pedals, amps etc for my daughter and myself.
My problem is that I can barely play guitar, and no way would I like to hear what I play.
When I make up an Amp, like I am doing now, I would like some way of testing the sound,
I would love it if someone who can play an electric or bass (or both) could record some dry tones and leave a recording that anyone can use.
If I came up with the best pedal ever, and then plucked or strummed my cheap guitar it would sound like a dogs dinner and no-one would like the sound sample.
Lets call it:  Sample1-Chord set,   Sample 2- Plucking etc. Or Sample 1- Stairway intro....
If we could all send the same signal into our gear and then post samples we might get a better understanding of what someone else has made.
This makes sense to me, but I know bugger all about it really.
Soo... Could someone who has the recording gear please make some test tracks up for me with a clean dry signal please.

Also while I am asking about this, what would be the best way to inject the signal, I can use a computer signal out, DVD player signal out, Phone (Windows .
How much should I drop the signal from say a computer sound card to mimic a guitar out. 5 meg resistor with a 1 meg pot ? A small op-amp circuit for high Z ?
All comments good and bad will be greatly appreciated, thank you
Michael

Yeah, the input power to the amp is 150W, 240V here in Australia
I haven't picked it up yet, I'm going into Hobart (Tassie) next week and I will pick it up then.
It looks like I might have to trace the circuit myself when I get it.
If I make a schematic up I will post it here.
For $35 Au ($25 US) I think I can't loose even with a Gorilla Amp.
The photo I posted is from the Auction House I got it from.
It will entertain me for a day or two at least when I get it. 

Thanks for that Enzo.
I'm not sure if it is a small practice amp, it's over 100 Watts and has a 12" inch speaker from what I understand.
But you might be right with the components, the Gorilla TC-35 has one Op-Amp and a TDA2030.
I can't find much information on the TC-110 on the net, I was hoping someone here has some info on them.
Maybe practice amps are bigger then I thought. 

G'day everyone
I think I just bought myself a Gorilla TC110 Amp on auction.
I don't know why I did it, it just happened.
I paid $35Au ($25 US) for it so I think I can't really loose anything.
I believe these amps sound crap from what little I could find out on the net.
Does anyone have any circuits or information on Gorilla Amps ?
I read that Pignose made them.
I will have to go and pick it up next week when I go to the city (Hobart Tas)
If I'm lucky at least I scored a reverb tank, 6 knobs. a decent transformer, etc.
I might stuff a 1 channel Sunn Beta pre-amp into the box, just to confuse people.
Or maybe a Marshall Lead 12W reverb, with a nice celestion 12" speaker.
A Schematic would be nice if someone has one.

I like to learn new things, and I am very curious what a "Series A 4 String Bass Guitar" is.
Like, what brand etc. (Please forgive my ignorance if it is a stupid question)
Thanks.
Michael

20watt, not big enough to be called the "Killer Bee"

This reminded me of this nice design I found ages ago, I have drawn up the way I thing he connected the transformers.
I think its how Phatt ? said it was safer to  do it.
I think it has also been posted on  FreeStompboxes at a later date.

Wondering if the 2.5Watt  will be called Bumble Bee ?
Then I can't wait for the Wasp and finally the Hornet.
I might have to get a Jensen MOD 5" 30watt 8ohm Speaker in anticipation.
Love the work Joecoolo85, keep it up.   :dbtu: :dbtu: :dbtu:

That is a very good point Enzo
Since I am not a musician, only a casual string plucker I would not know that.
I guess if the stage has mains power at the front so you can power a pedal board from somewhere in front of you then you don't want any extra cables to trip on.
I have only had a close view of people playing in clubs and pubs where the stage is very small.
I have seen The Angels, Midnight Oil, AC/DC and many other acts on small stages where they hardly moved around.
I guess I'm showing my age if I saw them on small stages early in their careers.
I have seen ABBA busking in a park in Stockholm before they got famous too, (I was really young)
I still think it would be feasible in small clubs and venues, or practice and home use.
I brought it up mainly because the expense would be minimal if incorporated in the build, and good for beginners at least.
It would also be one less item needed to buy, drag around etc.
I like all the answers so far, informative.
