Helios mic pre transformer
Posted: Sat Aug 26, 2006 2:21 am
Hey Guys,
Was gonna post this question on prodigy pro forum as well but its taking a while to register. This question is for anyone who knows a bit about those old helios mic pre's from around the olympic studio era. I've been trying to find out if anyone makes clones of the mic transformer: Lustraphone M10. I was speaking to Brian from Sowter, who is a really helpful guy btw. Hope he doesn't mind me quoting him, but I reckon this could generate a few orders for them:
"We supplied many hundreds of type 3374 to Helios during the '70s
until their closure."
"Spec. for 3374 is ..... 200ohm/ 5kohm, turns ratio 1:5, frequency
response +or- 0.5dB 20Hz - 20kHz with Electrostatic screens and
Mumetal can, size 34mm diam x 44mm high with fixing by 9mm
brass theaded bush in one end (could be done in a can 34mm
diam x 38mm high with two 3mm threaded holes for fixing).
Price is 44.36 pounds sterling."
"In the early '90s we made another using customers specification for
a Lustraphone/Helios replica console, our type No. 7490 for
200ohm primary with turns ratio 1:10.5 with secondary tap for
200ohm (ie:- 1:1). Frequency response +or- 0.5dB 30hz - 20kHz in
mumetal can 34mm diam x 24mm high fixing by two M3 threaded
holes.
Price 36.25 pounds sterling."
"Unfortunately we do not know if either of these were for the m10."
Does anyone know, I'm tempted to get both and give them a try?
