The label says 8 ohms 🫤

I tried, the 15” seems to take over the 18”, the speaker sensitivity may be too different, I barely ear the 18”

Just picked up a 1967 B18 here in France ! the speaker is a Ruby SP18h300 I don't know this brand. I wasn’t expecting such low-end extension ! Definitely more lows than my Vintage blue / JBL D140F cab, I think the fact that the speaker has a modern design has a lot to do with it, I even tried...

Do you know when it was introduced? I’m not sure how to identify it on the schematics.

My first amp : swr LA15 (1st version) 100w with a 15 ” and a tweeter, 3 band EQ, bought €300 in 2006, I hesitated many times to sell it but, I still have it, it’s my most transparent amp face to my vintage blue /home made B15.

5 years later : I just bought a DB750 I love it except the fans (like many people) I found a fan rated at 21 dB, but it is 38 mm thick : 8830N | Ventilateur axial ebm-papst 115 V ac, 36m³/h, 80 x 80 x 38mm, 8W | RS Components Does somebody ever tried this model ? If 38mm is to thick to fit in...

Thank you for your answer ! The transformers I Bought are from Fliptops. About the ground wiring and shield issues, Il may not respect the original building (ah ah heresy...) : My stepfather who will help (he is an electronics ingeneer) me think that it will be much easier to prevent hum...

Hi everybody ! I am planning to build a 1964 B15 amp, I have a few questions : - I can't find what are the resistors or Capacitor power ratings, does anybody have these informations ? - I am looking for the potentiometers, the 1964 diagram shows a 4M pot, is it exactly 4M or can it be a 4,7M...

Thank you for your answer ! How does sounds the channel 2 ? Brighter sound ? About the chassis I am thinking about bending a mirror polished stainless steel sheet with the same specifications of the old ones to fit on the tray. I already have the tube cage from fliptops. I bought the Ouput and...
