HI TO ALL ,,what do you think about 15'' speakers as 1 have a nice cabinet which has had a15'' in it &could be agood cab for my valve-amp project & 1 have 2 15'' musical instrument speakers to choose from, these are 100 watt units with aluminium centre dust covers& 1have mid range horns[2 types] & could control level of horns if used at all , just a thought
. 1know that most combo's have 12's but I have this nice cabinet that would take 1 -15'' &it has a 3/4'' ply-wood baffle. has somebody used this size & was it ok...CHEERS aussie barry..

Buddy Holly had a 15" alnico Jensen in his Fender wide panel tweed Pro amp so they must be good!
15" JBL's are pretty good too.
I think it's worth considering but you probably don't want to bother with the horns for guitar use.
Regards,
Charlie

HI CHARLIE ,In our winter we dont get a lot of rain in our locallity, but we get frosts -1c at times as we are about 1000 ft above sea level so we do get some very cold weather at times as well but you can rugg-up ,but the very hot weather ,it is hard to get cool,our winter suits me much better charlie... I will build up the amp chassis first & do a trial with 12's & the 15'' and make a decision at that point ,,I am going to adelaide later this week to do some welding on a steel yacht for 7 days weather permitting ,to earn some extra money,,hopefully come back home with valves, high-voltage electro's& coupling cap's,& 1-watt resistor's , I have a reasonable collection but not hi voltage cap's etc..nice to see you back safely charlie [you never know these days]all the best ,,aussie barry..

I still have my Bird Golden Eagle 25 watt amp from 1962, with its original 15" Goodman Audiom speaker (to my mind the best of all such speakers in the early 60s), and I found it always lacked a bit at the top end - not surprisingly. It's difficult to get the "all treble, no bass" sound like in "Midnight for" example. I imagine horns or a 10" speaker in tandem could make a good all-rounder. As long as you can attenuate them to suit the sound you're after. I'm thinking of building a cabinet with a 15" and a 10" for one of my valve amps. The Fender Bassman was popular with lead guitarists in the 60s.
Cheers, Lionel

My Bird 25 watt amp has a 12" Fane and 2 tweeters (the tweeters are dead). The speaker sounds OK after highly modifying the circuit but I had to do away with the reverb, which I wasn't really bothered about anyway.
The Bird is basically a decent amp with good components but the circuit design lets it down, particularly with the way the reverb is configured.

Charlie

Hey Charlie! Fancy you having a Bird amp too! It was my first amp in 1962, when I was sweet 16 and never been kissed!! Unfortunately they actually suffered from poor quality components that "decayed" over time. The Hunts capacitors were famously their weak point, but I liked the sound of the amp when it was new.
The Goodman was the best quality speaker they used. I was told they used Wharfdale but at that time they weren't known for producing proper guitar speakers whereas Goodmans were producing the Audiom series for guitars and the Axiom for HiFi. the reverb was great while it lasted and you kept the level down to avoid feedback, but the crystals dissolved over time. Mine has failed completely. Fane speakers came along a bit later - then they were the "budget" speakers of the period and cheap amps like the RSCs had them. My mate had an RSC bass amp with 2x12" Fane speakers back-to-back! An odd configuration!
There are a couple of people still modifying and working on them. John Chambers of Champ Electronics in Nottingham and a guy down in Somerset are two that I've contacted. The amps can be brought up to date with better components and reverb unit - but I guess anything can.
Cheers, Lionel

I bought my Bird amp for £100 with a view to using it for a research project, although not quite finished due to lack of time it has proved worthwhile, which leads me to the next paragraph.
I am working on an amp that I purchased recently, after finding that it was not quite what it was supposed to be. It might be marketed by me depending on interest raised after I complete the necessary changes (much of those are derived from the research on the Bird amp) and will be designed for clean sounds for country and jazz players. It will be designed to work perfectly for the Chet Atkins sound and I have 2 Gretsch semis, one a close copy of Chet's single cut 6122 Gretsch, to test it with, although other guitars will be used to test as well. The amp has a 15" Weber speaker with aluminium dome, designed to sound as close as possible to the original JBL D130 used in Chet's amp but has a neo magnet instead of alnico and according to Weber it has the same response as an alnico D130 speaker. An independent report stated that it sounds somewhere between a D130 and a D130F.
I will stress right now that this amp will not be designed to be suitable for Hank or Shadows music, although the Bird amp in its present state with the Fane speaker sounds very good for that style.
Regards,
Charlie
