dd hing,
Listen to the WE274 for longer while, then swap back to KU53 for a comparison.

what speaker are we going to drive?

Richard

Would you please to be the host?
We bring the amplifiers and..............................................................................................................BEER :-)
----------------------------------

No problem. How about the 2nd Saturday in Dec, i.e. 9 Dec? This will give Dr. King more time to build the HK amp.

Subject to JL's views, perhaps the party can be held at JL's luxurious home. Notably he has Tannoy 15" Gold, which is friendly to most EL84 amps.

Mdlover,

Is your EL12Special amp single-ended?

Regarding the EL84 party, you are welcome. At the moment everything is still fluid.

Just a reference list for EL84 amp which can participate in the party :

Stereo EL84 PP power amp :

- Leak ST20
- Dynaco ST35
- Pilot SA232
- Fisher SA100
- Arcosound 20-20
- Eico HF86

Mono-block EL84 PP power amp :

- Leak TL12+
- Stern Mullard 5-10
- Heathkit MA-12
- Verdik Q-10
- TFK V81
- Klangfilm V410
- Fisher 30A
- Eico HF-14

And this exclude all EL84 integrated amp or PPP power amp and any other EL84 amp from other country, such the the Nimus from Italy or Mini 1988 from HK.
---------------------------------



Heathkit MA-12 is below. It features the Leak TL12+ cirucit but was on Radford/Hinchley output and power supply transformers.

----------------------------------------

EICO HF-14 is below. It uses the SAME output transformers as in HF-81. The circuit is simpler than LEAK TL12+ (5 tubes).

4 tubes per monobloc. EZ81 rectifier, 7247 front/phase-split, 2x EL84 power amplification.

That photo of HF-14 was taken before it was cleaned/restored. Of course it looks much better now.

These are a cloned pair of HF-14, built on EICO HF-12 output transformers.

They are one of my first DIY amps and were brought to TK Chan's house few years ago. TK was amased by the sweet EL84 sound.

My typo: 7247 tube is used in HF-30, but never in HF-14. HF-14 did not have a long history of production as HF-30. 7247 tube type appeared when HF-14 ceased production.

My place is not that desirable for holding a party. Reasons:

(1) Despite its 30 m2 area, the poor setting and lousy furniture arrangement dissuade the accommodation of several people for auditioning purposes.

(2) I can only hold the party in the day time during week days when my boss is not at home.

Sifu R's place is a very much better venue for parties by all means.

各位師兄,

一般的後級增益大約26db, 但我的古董LEAKTL12.1卻增益36db, 而我的前級增益也比一般前級大, 前級和後級一齊, 輸出大量放大, 就算音量制開少少(開到七點鐘)已經好大聲, 唔開音量也有沙沙聲, 拷一拷部前級都有聲從喇叭走出來. 請問有何方法解決? 網友有何高見?
