Same here, 5V and 3V rectifiers in the EL3N currently being built for me. I wonder if the @whirlwind GOTL uses a higher current capable power trans.

Actually, the PY500 has higher voltage but lower current.

The PY500/42EC4 is higher voltage and current it's average current is 440ma not many 5 volt rectifiers
come close to that.

Don't know which other Lundahl you are referring to, this OTL uses the same 5V rectifiers as past GOTLs.
Also the 3V, I assume Glenn has wired this one the same way taking advantage of the different pinouts.
Don't have specs or model # for the Lundhal.

No it has a 20 watt resistor to drop 6.3 to 5. I had to many complaints about the PY500 and no tube rolling so I made it work with
5 volt rectifiers. I still feel the PY500 is the better tube.

Thanks for adding clarification, Glenn.
In that comment, I was referring to the heater filament current, not output current.
Per the spec sheets, 42V@300mA vs 5V@3.7A.

Hi every glenn tube amp lover. Let me introduce to glenn and owners of his amps. Im more speaker centric than headphone but I have good ok headphone set up. I have Woo audio WA6 SE with Westinghouse 6FD7 fat bottle, Marconi U52,GZ37 Coke bottle,GZ34 Metal base,GZ32 Brown base,Sophie Princess 274B Rectifiers and Aurender N100H,Intona ,Holo Spring 3 KTE DAC with Audio sensibilty Mod HE6,Audio sensibility statement occ silver cable Focal Utopia as my main cans. Im interresting on 300B amp with speaker option so owner of 300b amp or anybody have idea let me know please . I listen and own lot of DSD music over 2500 albums. Thank You

You will need fairly officiant speakers with a 300B amp as it is only 8 watts but 8 watts of beautiful sound.
The cost of one of these 300B amps is around $4000

I understood that have few pair speaker range 87 to low 90 db but not very sensitive . But if I get low power SET it will use with Omega spraker or Horn speaker. My main speaker system which Allnic Audio T2000 25Th AN Intergrated amp, Aurender music server, Huolo spring 3 DAC with Five pair of speakers.

So 300b amp will be similar to woo audio wa5 but better

Yes

Thanks for the explanation Glenn.

As a former owner of the WA5 (old version) and current owner of a Glenn 300B amp (modded) I would say very much better. Far better detail, dynamics, transparency and punch. In my experience only the very best SS amps beat it in these categories, and not by much.

The WA5 does have a strong suit - it is much more euphonic and 'tubey' than the Glenn amp. If you like that sort of thing, and on some tracks it can be quite seductive, then the WA5 is worth considering.

 

[tkcha]

but my need with speaker output option how about Q for speaker. Do you try with speakers ?

 

[tkcha]

and then I can use my collection of rectifiers ?

 

[2359glenn]

What impedance are your speakers.
I have made these with speaker outputs.

 

[tkcha]

I have bunch. KEF LS50,BLADE 2,HIM SOUND A33, Impress and DIY speaker morel tweeter, 5 inch Focal mid, two 8 inch Focal wooper made with HMDF cabinet hi end caps and internal wire. But if I get 8 watts amp. I will try to get omega acustic or Tekton Double Impacts which 95 db or higher.
