Pris ?

Etter at Motron har solgt 40 byggesett og jeg har bygd 15, beholder jeg den siste som et minne.

Tri B Oberton - 15 watt SET basert på 6C33C, får virkelig RCA LC1a duo driveren til å skinne, det låter utrolig bra.

 

[Endpoint Audio]

Her er mine Ikarus monoblokker fra TLA. 25W. 1x211, 1x300B og 2x6sn7.

 

[The Gunner]

Urk, her er det forvrengning så langt øynene kan se

 

[Endpoint Audio]

Jah...

 

[wizard]

En meget bra 6C33C basert integrert fra Russland.
12/24 watt 8/4 ohm.

Litt mer info da wizard

Dette er en prototype, ikke for salg enda.
Men prisen blir bare ca 15000.

 

[Haavard]

Litt Sonic Frontiers assosiasjoner på fronten.
Ser veldig bra ut, men kjenner ikke røret.

 

[wizard]

En 20 watt stereo effekt som snart kommer på markedet.
I bakgrunnen 60 watt monos.

 

[wizard]

60 watt mono prototypene på hjemmebesøk.
De kan brukes med utvendig chassis...eller "nakent".

Uten utvendig chassis.

 

[wizard]

Prototype testing.

 

[wizard]

Siste versjonen av utvendig kabinett, kan også leveres i sort.

Total vekt er ca 80kg stk, etter 5 års utviklings tid er de nå endelig ferdige.
Utgangsrør er KT150.

 

[Bjørn.H]

Jeg skjønner prisen blir høy.

Uesugi 211 SET - meget bra lydkvalitet til bare $3500.


"211 SE tube amplifier with output 18W. All transformers are special order made from ISO (TANGO). Prestage is 12AT7, secondary tube is 5687. Rectifier tube 5U4G, GZ34, 5AR4, 5R4GW.

This is newly made production. All parts are new, all transformer are new order made from ISO (TANGO ).

This amp adopted fixed bias but you dont need to care to bias, it is set one time and use all life.

Sound is perfect, vivid in high range, powerful and weet in middle low range with very wide sound stage."

Tosca AT5 Signature

Rør - inngang 6SL7, driver 6C19 og utgang 300B.

Hjemmesnekret triode preamp (6AS7/7236) og triodekoblet KT88 SE. Headsettampen på gulvet er også full av trioder, men ikke helt SE

 

[The Gunner]

God damn, her blir man våte i øynene. Så mye deilig snacks!

Triode Lab 2a3M II. Dette er det jeg har vært mest fornøyd med av alle forsterkere jeg har hatt innom.

Fører dere fortsatt Triode Lab??

Hvordan fungerer denne forsterkeren?

"The Alieno's first gain stage uses a symmetrical stage using ECC82 tubes, followed by the output stage, which uses a 300B tube per channel, in a single-ended Class A cathode output configuration . The KT150 only works as a linear current generator to power the 300B.

The 'trick' lies in connecting the power stage to valves to the load (columns) by means of a low value resistor, whose voltage variation modulates the current supplied by the solid state power supply, simultaneously connected to the load in parallel with the 300B, whose 'signature' (transfer curves) is thus 'emulated' by the PSU.

In the absence of output transformers, the floating ground prevents the speakers from being affected, in case of oscillation or amplifier malfunction.

This innovative technology, called LTD, Loudspeaker Tubes Direct , was created by Fulvio Chiappetta, designer at SI Audio, Italy."

Uesugi 4212 mono.

"The power monster 4212 tube amplifier, drive tube is 211, input tube is 12AY7. All transformer are special order made, orient cut core. Price is 15800 USD for pair.

4212 is the biggest tube using for audio, it is 2 times bigger than the king tube 211. Output for class A is 40W, which is impossible for almost tube. It is not transmission tube, it is tube using for audio. Transmission tube as 833A or 805 can procedure output power up to 50-60W, but it is class A2, not class A.

Sound is very rich, powerful and detail.

One block is about 50kg so it will cost shipping fee much.

It does not use switching transformer. Heater transformer is order made.

Specification:
Response frequency: 16Hz ~ 60Hz(+-0db) 10Hz~100KHz(-1db)
Output is about 40W/channel. (input 0.5Vrms)
Hum level : 0.3mV
Total harmonic distortion: 0.002% 1W 8ohm
Consumption : 320W

No tubes are included."

Ja det er vel noe hokus pokus 300B er koblet som en catode follower, altså må "courrent", kult navn levere enda mer strøm, så den virker som en vanlig forsterker med lav utgangsimpedans? Aldri sett dette nevnt i 4 bind med Morgans Valve Amplifiers, så er nok hokus pokus.
