this is my 6H8C line preamp, tue rect is a 5V4 type:

 

[torrence]

Pretty standard EL-84 UL push-pull amp. I have used Russian tubes tubes throughout (6n1p and 6p14p-ev) running around 360V. I was tired of drilling aluminum plates, so I brushed off my junior high shop skills to bend some acrylic.

Two stage tube phono preamp

Two stage tubecad tube preamp. Russian PIO inter-stage caps and Sprague RIAA comp.caps. Separate PS and preamp powered by 24VAC wall wart. Linear PS develops 295V. All built on veroboard no PCB. Excellent sounding. Also to use a MC cartridge I have built a Le Pacific jFET pre-pre.

Le Pacific pre-pre for MC

My build of the Le Pacific pre-pre was contained on a single piece of veroboard with battery pack. I matched the 2SK170 BLs. Output caps are Russian PIO. Same caps as use on the tubecad tube preamp in an earlier post. This pre-pre has been designed to work with the tube preamp which uses the same caps. It got cramped in the case but sounds excellent. Very pleased with both the Tube preamp and the Le Pacific pre-pre for MC.

Nice, the smooth bends suit a tube amp nicely. Screams 50's. Very vintage looking!

Mhouston,

I like the power(?) switch of your amp.

Yes the rocket launcher gets them every time. That's a bread board KT120 with interchangeable driver section. It drivers a pair of KEF iQ30s.

The Power Amp


Mains TX for this and previous Aikido were both custom wound by Shinrock and they are totally silent. 0.7mV hum both channels.

Hi everyone!

My first Tube Amp working at low Voltage of
24Vcc.
The output power is about 2W @ 8 ohm.

I used one PL504 and one 12FQ7 (ECC82/83 are also OK)

Interesting use of the tubes,

When is the stereo version being made?

Where did you get the circuit diagram?

Regards
M. Gregg

 

[pilovis]

The circuit diagram was found on the web, but I modified it quite a lot

I will post it soon.

A 6BM8 Stereo SE amp I built.
Switchable triode/pentode mode.

Audio level indicator tubes.

Viewable in action at:

Tube Amp REV 2 Part 5 - Finished.wmv - YouTube

I enjoy listening to is almost as much as I enjoied building it!

Hey pilovis, I see you care for audiophile grade parts. Also, feeding that big tube with only 24V is going to make him angry - good for hard rock.
