Re: Spitfire Transformer...cheaper alternative
Hey Guys-  
For a lot less than the 165.00 West set you can get the PT & OT set for the Marshall 18 watt repros that Graydon Stuckey sells...a LOT less, and I've already gone through 10 OT's alone in builds for various 15-18 watt amps and can attest at how great they sound ! Plus the OT has 4,8,16 ohm taps whereas I don'tthink the 'Matchless' does. The 18W OT's are a 30-watt frame size, too, the size of the Pro Reverb tranny. My Postman uses one, too:

Hi Alexander ,  
 
thanks for the suggestion !  
The Westlabs OT does have 4 , 8 and 16 ohms taps if you do use it as a 8k primary one . The Matchless 15 watt amps do use 4k primary so they only have 8 and 16 ohms output-taps .  
 
Have a nice and rockin' weekend !

Hey chris,  
when I hooked up mine (west labs) I connected all three taps to an impedance selector switch. Are you saying that in order to run it like a true matchless I need to connect my 8 ohm cabinet to the 16 ohm tap ( for 4k Z)?  
thanks,  
jason

Hi Jason ,  
 
Just did check some (factory) Matchless schematics and they did use a 8k primary . Must be a slip of the mind :) but I thought I did see some postings over here regarding a 4k primary impedance on the 15 Watters .  
I did wire the OT with a switch and some jacks to make all ratios possible and my favorite was the 8k primary .  
Sorry for the confusion !
