What speakers did you fire up with this amplifier?

What speakers did you fire up with this amplifier?

DIY backloaded horns, drivers are Fostex FE 208 Sigmas, if my memory serves correct. I made them 15 years ago.

Indeed it's Fostex Sigma's....nice setup.
I wonder what did use for EL84,

Toroids with gaps?

MUITO

Hi,

yes !

Toroid with gap from TOROIDY ( Poland )

Couldn't you make this with a ferrite ring and a hacksaw?

 

[Wavebourn]

Ferrite saturates in lower field strength than iron. You would need too much copper for low frequency transformer.

This year on BAF a single ended 2-stage pentode amp was driving speakers in Firehouse auditorium for lectures.

SRPP wit ecc 82

Built this pre for a year ago and I am very satisfied with the sound. In the amp today I have a pair of yugoslavian ecc82, just for testing, sounds perhaps a little bit "thin", but I will swap to a pair of Sylvania 5814A who sounds great.

Fitted with his dedicated power supply ( 3 toroids power transformers )

How's the heat build-up inside that box ?

 

[ROCKMANDRAKE]

Super Muito

Hi,

no heat build up inside...

You have to lid ( very easy to remove ) off the amp before listen to music.

Here's some of my stuff'

Left- Regulated Power Supply
Middle- 6SN7 or 6FQ7 (wired in extra sockets)w/ Reg PS- PreAmp
Right- SE 6AQ5

Not pictured are a PP 6V6 & 6BX7 SE (plug & play with the Regulated Power Supply)
MDF chassis, top edges routered, sides are about 1/2" space on side bottoms-for air flow, with 1/8" holes drilled on top, finished in truck bed coating. I built these in the late 90's. They still sound nice.
