New OT

Post by jestaudio »

Got a line on a replacment transformer for my Rockster build, its a Hammond unit rated at 4000 and tapped for 2 ohms only, i assume that running a 8 or 16 ohm speaker should be ok but will it be ok with 2 6l6s
Cheers Gary

That OT, 4K:2 will also function as 16K:8 or 32K:16. IMO, 16K or 32K are both poor choices for a pair of 6L6. It might be an interesting choice for one 6SN7 (PP triodes). Or use it with a 2 ohm load as designed.

what phil said I wouldn't run it with a 16ohm.

you can go down with a load mismatch safely but not up.

I'd say better safe then sorry in this situation.

I remember you posting that you already lost an OT in that amp already?

I'd check what Rj's shipping to the UK is for one of his edcors.

Have you contacted Phil at Bluebell Audio?
He will be able to put you on the right track.

If you decide you can afford to pay some extra, I have just used Mercury Magnetics and I am totally happy with their products, with or without the self-generated hype, which is, admittedly, slightly annoying.
Cool running and great sounding to my ears.

You can get good prices from JMI in Texas.

phils my first port of call, he sorted me out with some great tannies for my ODS build and is reasonbly priced, MM,s are way out of reach and i,m not sure my ears are good enough to pay half agains as much for a OT :D
