Any body know where to get the transformers for the classic GainClone. I've been told it needs to have these specs:
QUOTE]The transformer should be rated to around 150-300 VA and be either a torroid, R-core or C-core type with dual secondary windings of 16 VAC. This will provide 25 wpc with LM3875s. 12 or 15 VAC secondaries can also be used successfully.[/QUOTE] |

Many people, including myself, have used Plitrons both with and without the shield. Do a search for "Plitron" on this forum and I think you will get the idea. The prices are in Canadian Dollars.
http://www.plitron.com/pages/Products/Std/Standard.htm A few years back Hammond had a less expensive and readily available alternative (stocked by Newark I believe) that some people were enthusiastic about and others found noisey. Definitely worth exploring and getting some more current product feedback. There are great buys in surplus transformers available but you have to find them yourself! |

A quick search of the archives will turn up quite a few links to trafo manufacturers. In the mean time you should check out avel lindberg. Their Y32 line has quite a selection of toroidal trafos that would work very well... in fact I'm using one of them in my gc.

Partsexpress.com has Avels, but might get you for shipping, also try and contact them directly, i found a distribution plant in Conn that is selling them a few buck cheaper then PE and will ship USPS.

I'm not sure how much parts express would charge for shipping, but I ordered direct from Avel and the "cheapest" shipping rate was $11.60... that depends on weight too though (I ordered a 500VA toroid). I think I remember that it was shipped via UPS...

I used Avel Lindberg as well, I cannot remember if I ordered from PE or direct from Avel Lindberg.
I only used a 160VA because I wanted to sqeeze the entire stereo amp into those small Bud extruded aluminum chassis. The transformer is within a half inch of the rectifier PCB, and the two channel PCB's are farther, but not much. There is no shielding at all on the transformer, and it's dead silent with no hum. However, next time I'll find a bigger chassis. |
