- #1 [李公子], 24-05-11 19:12各ching 請問我部Amp只有4/8ohn,如果推3/5A15ohn,對喇叭會燒?
- #2 [littlered], 24-05-11 19:27推35a,最重要用膽機,其實25W就已經足夠,例如Luxman的KT88膽後級,已經十分好声!
- #3 [bt99], 24-05-11 19:47點解會燒喇叭?
估您係部石機,數係咁計,50w/4Ω,25w/8Ω,12.5w/16Ω,又或者 50w/8Ω,咁 4Ω就有50w,接 16Ω 仲有25w 照唱無誤。 -
- #4 [伊雲士], 24-05-11 22:14當然阻抗匹配最理想
一係換机或一係換喇叭啦
AMPEX EL34 power amp (16 ohm ) - #5 [lym], 24-05-11 22:39照推囉。

一定要用膽機?點解? - #7 [littlered], 24-05-12 01:0835a推出嘅六七年代 相信是用膽機較聲。 原子粒機唔係一定推得唔好嘅,但係比較揀擇,我個人喜歡就用pure class A嘅機去推 。Nelson Pass嘅 Aleph 3, or 30,我覺得相當匹配!
- #8 [alexanderkoo], 24-05-12 05:36Tannoy 12" red 16 ohm SS amp 8ohm output. Electrically ok but sound was odd. Parallel connect 16 ohm metal resistor across individual speaker posts. Much better now. Can custom order 16 ohm tube amp. No longer using vintage tube amp with 16 ohm output due to reliability issue.

2020年Covid 19 三月份某一天起身後見到呢幾嚿超級大物體十分礙眼同阻地方,手機即刻打去SSP叫個二手佬一日之內全部監便監賤連埋所有SACD,,什麼黑膠線材一次過搬走佢, 完全冇後悔亦都冇諗過錢, 一屋通爽哂,之前又話呢啲線, 個D插頭, 又話喇叭腳等, 全部自己呃自己(同老婆),真係坦白聽唔出有好大好大分別 而家諗起個對大喇叭又黑又實成個楝係度好似棺材咁, 每次聽得個十零分鐘次次搬出搬入都冇哂癮, 送返比我都多謝哂, 如果得罪師兄先講句sorry, 只係講下自己嘅感覺
最後修改時間: 2024-05-14 16:31:53 - #10 [greenhope], 24-05-14 16:35以前用過英國造既audiolab 8000a推3/5a, 其實係唔錯既
- #11 [micromegamah], 24-05-14 16:51記憶之中八十年代音響雜誌係叫人用大功率AB後級去推3/5A
又或者用50瓦純A後級去推
可能發燒音響首先話用膽機去推 - #12 [S.Chan], 24-05-14 19:35鐘意用 EL84胆推 Roger 3/5A 11 ohm.多過 EL34, e+兩部都神神哋,用石機金仔 E-305聽住先, 不過好耐無開機囉。
- #13 [olddude], 24-05-14 23:49#11 低效率喇吧用膽機推?有創意,夠發燒
- #14 [littlered], 24-05-15 01:45Low dB but some are 15Ohm. Frankly 3/5a not hard to voice but very hard to sound good! My experience is a 30W valve amp may fit the shoebox well!
- #15 [伊雲士], 24-05-15 11:46用kt88/6550啦
60W x 2
