You can use them in the DV, GOTL amps, Feliks amps to name a fewI wonder what other 6080 tube amps afficionados are loving the Bendix..

Woo audio (2 and wa22) as well, i think these are quite popular tubes.You can use them in the DV, GOTL amps, Feliks amps to name a few
@L0rdGwyn good news on the 339i front...virtual center tap works on 339i too.
@telecaster Did you document the process with pics so we could try? You mentioned Fender amp...is that where your user name comes from?
I see that's a lot of amps! I was wondering why those 6080 prices skyrocketed in the last decade!Woo audio (2 and wa22) as well, i think these are quite popular tubes.
Glad to hear it worked out @telecaster , if there is still some residual hum, elevating the heaters should remove it completely. You will find the center tap is already done in most amplifiers, grounding one half of the heaters is not the recommended approach.
BTW @Galapac , Mouser finally got me my package, just need to put in this new reservoir cap, upgrade the heatsink on the regulator power MOSFET, and replace the gyrator caps and your hot rodded DarkVoice should be done. Will get to it Thursday or Friday.
It sounds very good with a nice 6SN7 and a Western Electric 421A, so I hope you have a 421A or 5998 lying around! Can also use 6J5 with an adapter. I will be very curious to know how it compares to the La Figaro 339i.
Oh it was very easy, i can post a photo tomorrow to show how it's done.@L0rdGwyn good news on the 339i front...virtual center tap works on 339i too.

I think I got one of those...I also have some decent, non GE 6SN7s/5692/6J5GT hanging around. I’m pumped to try it out. Will be like a brand new amp! I have a stock DV that I use with my turntable so I will probably compare those first with my ZMFs, then swap the stock out to use the modded DV with the turn table going forward. They will need to pry it from my dead arms to sell it, it is now legendary thanks to you!Glad to hear it worked out @telecaster , if there is still some residual hum, elevating the heaters should remove it completely.

You got me interested in trying the gyrator to load the 6j5!
Thanks L0rdGwyn!
Yes there is a tiny bit of hum left so I will try the elevation!
I think I need to do my homework before modding the 339. I use different drivers (6J5, EF86, 6SJ7) so a fixed bias might not be ideal for me! I might roam in your DIY thread and ask you questions though if you don't mind ^^Since the La Figaro circuit is more or less the same as the DarkVoice with a few changes, pretty much all of the mods I made to the DarkVoice could be applied to the La Figaro, you could try a gyrator load on the driver tube, or a constant current source. Gyrator regulates the plate voltage though, which is helpful for direct-coupling.
Only issue is the B+. It is around 150VDC in the DarkVoice. I regulated the power supply to get a higher B+, 183VDC, by removing all of the RC filters in the supply, which gave more headroom for the gyrator load. Not sure if the La Figaro also has a 150VDC B+, but if so, an active load could work but not a lot of voltage headroom depending on the bias point.

The 4 tubes went for $959.00...unbelievable. Way overpriced for these.Bidding war going on for these nice looking Bendix 6080s...let's see what they will go for. Currently $610.80 U.S. for 4...any of you 339i guys/gals in the running?
I have mine but like to watch.

由于拉菲加罗电路与黑暗之声的电路大致相同,只要有一些变化,我给黑暗之声做的所有mods都可以应用于拉菲加罗,你可以尝试驱动管上的旋转器负载,或者恒流源.回转器调节平板电压,这对直接耦合是很有帮助的.
唯一的问题是B+.这是大约150 VDC在黑暗之声.我调整电源,以获得一个更高的B+,183个VDC,通过删除电源中的所有RC滤波器,这为回转器的负载提供了更大的空间。不确定拉菲加罗是否也有一个150 VDC B+,但如果是,一个有源负载可以工作,但没有多少电压高度空间取决于偏置点。

What I think @xmdkq is trying to say is the he is one of the original designers of the Dark Voice, but due to disagreements in the original company, they parted ways and he started a new company, Chengdu Yuqin Audio and Video Studio, which makes the La Figaro, and other products.Is the same designer, black voice because of the separation of the new design Figaro 339.

It seems it has ended with Usd 959. Wonder who is the lucky ownerI wonder what other 6080 tube amps afficionados are loving the Bendix..
