A 39uF cap would cross around 500hz.
Does the squawker get a little “crackley” sometimes? That’s when I know I’ve pushed it too far.
No, it really sounds quit nice. I was just curious if I might be missing something.

Hi Dean. I bought a pair of you Universal crossover from Kevin . You built them for his khorns, but he went a different direction, so now I have them in my CornScala using a B&C DE85 TN mid driver(500-18000) and your crossover has a 47uf filter. The woofer is a Crites stamped basket. Not sure this crosses over properly. Do you think I should have a different filter with my combo?

....test the Willsenton warranty
i dont care about warrantys. i know two different repair shops that can not only fix any issues, but have the ability to improve the design. i rarely worry about a warranty on anything. if it breaks, i throw it away and buy something else. pretty simple

I only have to deal with two tubes right now, as I only have a tube linestage. One rectifier and one 6dj8/6922 for the audio.
I can't remember what rectifiers work the best and that may depend on the PS circuit in your amp. Look at a tube substitution site to tell you what you can use and then see what others think change the sound for good or ill.
I need to get my Dynaco ST-70 back together...

I bet it’s going to sound fantastic.
It sounds better than my China EL 34(Audcom) and i really like how the Audcom sounds with JJ KT77's in it. The Willsenton out of the box had a blown rectifier tube(RCA 5U4GB), so I swapped those out for a pair of Sylvania 5U4GB and fired up the amp for the first listen with the original Willsenton 300b's and I was pleasnatly surprised with the bigger more detailed sound stage. I next switched out the Sylvania's for the Jan 5U4GB which is a Phillips ECG and not much if any difference. Next switched out the Willsenton 300b for the Gold Lion 300b and it was a step up in clearity and a bit more open, but not a huge different from the Wellsenton 300b. For the Willsenton pre amp tube, I switched it out for a pair of china 6n8p and i thought it brightened thing up a bit. Will do some more rolling back and forth today and maybe get a better idea of what sounds best to me. Would like the try some of the coke bottle retifiers tubes, but not sure what i can use in this amp. Any opinions on what rectifiers sound best?

I finally got my Gold Lions for my Cary's. They sound better than the EH's right out of the box. I'll be breaking them in over the next few weeks. Congrats on the Willsenton, I've read some good reviews on it.
Thanks, the amp is being delivered with the original tubes as well as the GL 300b's . Cant wait to try it out.

How many other companies are presently manufacturing audio tubes in the USA?
Not many. I was surprised to hear that WE were made here, but $750/tube is just way out there.

I think they also be made here in Rossville, GA, as are the 300B tubes.
Why are the WE300b tubes so expensive? How can a Gold Lion cost half as much? They are not vintage nos. They are brand new.

Yes they are. They alao have a 5 years warranty.
They are working on a replacement 12ax7, hopefully rolling out this summer.
I believe they are building a new plant to build those here in US. I heard the GL 300b is a decent tube. Will soon find out.

I agree with the idea this brand is built in the same Cayin factory, the paint and control knows look identical to several Cayin
models. I would like to give a 300 amp a spin but the current prices for quality 300b tubes is giving second and third thoughts.
Here’s hope you enjoy it -
Hey thanks. It looks like a quality unit. Plenty of review vids out there praising it. @1300 with replacement tubes its worth a try. Looks as new.

You almost sound like you are going to sell it. If so, maybe the garage sale.
I may, if i don't like it. Put the money into something i do like. I would really like to have a Cary 300b.

I just purchased this amp. It is barely used and comes with a full set of upgraded tubes including the GL 300b. I watched and read all reviews and it looks like it might be a decent 300b for the money(1500 new). I have been told they are made in the same factory as PrimeLuna and Cayin, but im not sure. Either way good reviews and not too expensive introduction into 300b.

I see i posted this a while back. Gettin old. I did buy and try the 12sc7gt. Did not like them. I have since ordered some more replacement Jan and Marconi to try. I again switched tubes from one side to the other and so far no noise, go figure.

Thanks for the input guys. I will check this out. I am currently also looking at a Willsenton R300 which has received great reviews . The Willsenton is a China amp, but have been told they are made in the same factory as the PrimaLuna.

I have a MapleTree phone pre amp and have had an issue with the tubes that came with it. It uses 2/ JAN CRC-12SC7 can type and 1/RCA 12sn7 glass. I get noise out of one or the other of the cans and have bought several sets with same results. Would like to find a better replacement. Would like some opinions on what tubes to buy to replace these with. I have switched the cans from one side to the other and the noise always follows the tube. I finally found a good pair and now one of those is noisy. Looking for quite good sounding tubes.
