New Lundahl Audiophile Transformer and PS Chokes

Lundahl Transformers will shortly announce the availability and pricing for three new parts.  The data sheets are linked below:

LL2766 – a compact (LL1660 size) low power output transformer for tube amplifiers, SE or PP.  Think SE 45/46/47 or PP 6V6GT and many more low power possibilities…

LL2771 – a big (1A, 3H) power supply choke.  Would have been great for my PSE6C33C amp power supply….

LL2772 – a low resistance filament current choke (3A, 80mH).  Perfect for the Russian GM-70, for example.

Gerus Audio is using Lundahl Transformers in their Amplifiers

Scott Gerus has been building tube amplifiers for some time now, but recently retired and has created a website ( to make his designs more broadly available.  He has designed and built several monoblock and stereo single-ended and push-pull amplifiers, which can be viewed on his website.  Interestingly, he does the woodworking and metalworking for his products himself!  Have a look.  These aren’t simple aluminum boxes with tubes and transformers parked on the top!  (like I build for myself…)

After using Lundahl output transformers in a few amplifiers over the past two years, he recently posted on his website:

“Over the years I’ve used Hammond, Electra-Print, Transcendar and Pliton OPT’s.  The only one that comes close to the Lundahl is Plitron, and they cost twice as much and take up 3 times the space!

You can’t beat the Lundahl’s for the Price!”   We agree, Scott!

Erhard Audio uses Lundahl Output Transformers in their designs

We are happy to note that Erhard Audio (formerly Tube Nirvana) has auditioned Lundahl amplifier output transformers in their models and, as a result, are using Lundahl output transformers now in production.  You can read their take on these and other parts decisions here: and see power the amplifiers here:

And while you’re at it, look at the chassis artistry, as well!

Mir Line Stage is finally available!
