I'll second the Woden designs. I just built a pair of Silburys, which sound wonderful. The Vulcans are probably a better match for a TSEII though (from an efficiency perspective). Nice build, btw!

Default Another succesful TSE-II

Finished up my 300B TSE-II build a few weeks ago. Lucky for me, it fired up on the first try. I have about 50 hours on it and it simply sounds fantastic.

I'm running Gold Lion 300B's. The OTs are Electraprint 5K primaries. My B+ is about 390 volts and I have the bias set at 65mA per tube. Nothing exotic on the component side, K40 coupling caps. I'm using Amperex JAN 5842 drivers and an RCA branded Mullard 5AR4.

The top plate is from Front Panel Express and the chassis is made from leopardwood with a tung oil finish.

Just a marvelous sounding amplifier playing thru my Franken-Altec speakers.

Thanks to George for a great design and to all the forum members that posted helpful information on their builds. Reading every post sure helped me to be successful on my build.

Looks very nice... I was not familiar with leopardwood, I like the color and grain pattern.

I'm also designing a top plate for a TSE-II. Would your share your design file?

Thanks, Jacques

Default Another FPD for SSE

Here is another SSE build, I did it a few years back. Jacques you asked about a Front Panel Design file for the top plate. I've attached a ZIP of FPD design along with the backplate design

That's a first-class build for sure. FPE is ideal for those who want countersunk holes, as they're a bit tough to do properly without the proper tooling. BTW, what transformers are those?

Excellent work!
