Thank you all guys.
Which Classic Tone transformers are the best fit for this projects?
I'm getting confused by too many models.

Re: Small Special project, Morgan guts
Since you're from Italy it's a lot cheaper to buy some Hammond irons at tube-town.net for example.

Re: Small Special project, Morgan guts
you think so? I'm comparing prices, Hammonds are quite expensive.
Last plexi I built it's been more convenient to go Marstran.
Anyway, I'm not sure about which Hammond to buy as well, that's why I was asking about Classic Tone, to compare their specs to Hammonds at Tube-town.

Re: Small Special project, Morgan guts
The PT I used for both amps is # 40-18005
The choke is # 40-18003
The OT is # 40-18001. It's the one with M6 iron.
These are for a 50 watt, not 100.

Re: Small Special project, Morgan guts
Whitewave, I used this transformers for my build and I am very happy with the results:
http://www.trm-audio.si/omr_transf.htm
PT MT8-2x6L6 FENDER (340-50-0-340V/140mA; 0-5V/2,2A; 6,3V/4A)
OT 2x6L6 4K
Choke 4H
The contact e-mail address is trm.elektronika at siol dot net
They are located in Slovenia, transformers are very high quality, shipping was fast and pricing reasonable.
In Italy you have http://www.inmadout.com/. I ordered a set for a build that I am into now. So can't tell how they run, yet, but look very solid and good quality - again reasonably priced and they take custom orders - lead time is about 2 weeks.

Re: Small Special project, Morgan guts
It is like 98% correct, just a few differences I see in the photos: Bright cap is 250p; the PI input cap is definitely bigger than .0022, seems to be a .022; there is a 1.2k in series with that PI cap from the level pot; the 100R NFB resistor and 10uF is most likely wrong, the way it's drawn won't do anything. Most likely it connects to the tail of the PI like in the Small Special schem, probably there is a wire under the board; Last little thing is the power tube grid resistors are 1.5k. The pics I used for reference are: http://ivanrichards.files.wordpress.com ... an-006.jpgrandalp3000 wrote:does this look close?
