My loaner amp is up and running. Right now with a 61 Melz 1578 and a GE 5998A

Stunning....stunning....

Okay, @Paladin79, finally ordered a Melz 1578 today. Looking forward to hearing it, supposed to be from 1959.

I also found these today at our Goodwill. Accessories in plastic and appears someone just never used them. They sound like Bose.. that aggressive V curve out of the box but most music comes out sounding pretty good. That aside, their selling point is active noise canceling and it works great. Best thing is they were only $8.

Does Goodwill accept DarkVoice with ‘rice filled’ tubes / GE tubes (charity tax deduction = zero...)?

1959 is an excellent year, well done, if you run into any issues with noise or hum and cannot re-solder the pins yourself I would help. I had a couple recently that I had to go over a few times before the solder would stick to the inside wire. I cannot quite make out the year in the photo but the Russians are pretty good about getting the dates right on those tubes if it is coming in from Russia.

I need to repair some headphones that I gave to someone along with an Incubus amp, if not repairable I was thinking of giving him my Senn 6xx but then I looked on Ebay and saw what some were going for lol. I will rebuild the other headphones one way or the other.

These look very good as well and there are several of them...

An excellent photo showing year, and all the proper attributes of the 1578, now find one of these without the perforated plates and you are getting into holy grail territory IMHO.

used only a month dark voice 336se. I immediately switched stock tubs. Svetlana and black teasure combo and bought some fotons. Stock tubes not humm at all,deadly silent. But foton and black teasure buzz. I think i need to make that fizz mod. but i am noob in eletricwork. what way to put bybasscaps , i think there is negative and positive legs. i saw some pictures where to put them on. put which way
which would be better 220uF/25V caps. https://www.aliexpress.com/item/32801815383.html
or

In fact there is no dead silent DV
A slight hum over a certain dial is normal.
Try different tubes and see if the hum and buzz persists all there sane, try to keep it on for a total of 72 hours on one set of tubes and decide after.

Nice purchase, but holy cow - the Melz perf plate 1578s have gone from high to insanely high prices!

It has been that way for a while, now the Russians are selling lesser Melz for similar money, or trying to.

 

[Ripper2860]

Last I checked the perf plates were at low to mid $100 each. Now they are typically $200+ each! My vacuum tube investment retirement strategy seems to be paying off.

I can still buy large batches at low prices but....not the years I want. $140 each with shipping included is not outrageous and I can buy now or wait for the price to go up even more.

 

[Ripper2860]

Yeah, but that listing was $280 each! Of course, they also accepted offers, so it may have sold for less, but geez!

Shop for tubes much? lol The listing is for a pair for $280, photo even shows a pair, says 2 times and mentions a pair. Oh and it even says matched pair.

 

[therremans]

I (quickly) purchased mine because he was only asking $40, shipping was an extra $15. I couldn’t let this one go. It was labeled as used but testing good, we will find out what it tests. Hopefully no issues with hum, etc but will resolder if I find any problems.

Yeah a lot of caps are polar. The side with a line is the (-) end. This points away from the tube socket. For volume pot, ALPS RK27 blue 10k or 20k, (knurled shaft if you want to use the stock volume knob)
