miss match impedence speaker ne biasanya bukan jer boleh rosakan powertube tapi akan menyebabkan OT. output transformer kaput.
Utk tube amp, law dia simple.
- Kalo amp nak 8ohm, maka feed la dengan speaker dengan nilai 8 ohm total.
Mean,
- feed ker 1x8ohm speaker.
- atau feed 2x16ohm speaker wiring parellel.
- atau feed ker 4x32ohm speaker wiring perellel.
- atau feed ker 2x4ohm speaker wiring series.
Cakap berapa banyak speaker, berapa ohm setiap satu pun tak guna sekiranya tak bg tau aper jenis wiring, parellel or series.
Walocammanapun, aku biasa feed amp yg 4ohm dengan speaker 8ohm.
- tapi utk kes kes tertentu dan tak sesuai dijadikan amalan... hehhheheh.

Kalau amp 4ohm --> speaker 8ohm = molotop (amp<speaker=$)
kalau amp 8ohm --> speaker 4ohm = ?
kaputkap jugak ke? or still ok cuma bunyi je sebu2 bahasa?

Biasa selalu confuse between solidstate dan tube amp.
Aku tak nak la nak terangkan cerita speaker and amp impedence terlalu detail. Sebab benda paling tepat adalah.
- speaker impedence mesti = dengan amp impedence.
Tapi memang biasa kita dengar.
- utk Solidstate amp, speaker boleh up ohm tapi jangan rendah dari rating amp tersebut.
- Utk tube amp, speaker boleh rendah ohm berbanding ratting impedence amp.
- but jangan pergi terlalu jauh.
utk tube amp, kalo amp 8ohm guna 16 or 32ohm, mean OT akan demam berasap.
- tapi kalo turunkan ker 4ohm, amp still boleh mai tapi power cam tak cukup and kengkadang tendang fius.
- Aku pernah try guna 4ohm speaker ker 8ohm tube amp, dalam masa 1/2 jam, mula feedback dengung keluar.
- terlalu rendah speaker imp pada tube amp pun akan tangkap OT juga.
utk solidstate plak terbalik.
- kalo amp 8 ohm, boleh gi ker 16ohm or 32 ohm.
- tapi jangan plak fendah dari 8ohm, menyebabkan power amp kerja berat dan power transistor akan terbakar.
So bebenda yg merah diatas adalah sebagai perbandingan, so jangan plak gatal nak test, sebab kalo amp kaput jgn salahkan gua, sebab ultraman cosmo kata boleh.
- Aku sentiasa dan hanya percaya amp imp= speaker imp, akan selamat la kedua duanya.
