I’m updating this post not to make people confused. I believed B+ was lower with 5v4g than 5y3. but 5v4g is increasing B+ and makes the bias warmer than 5y3. I guess it is the reason I feel the amps are more alive with 5v4g
then I noticed the vintage amps with the original caps from 50’s and early 60’s are more vulnerable with 5v4g to 60hz hum. I’m just guessing leakage of the coupling caps and the filter caps could be the reason. I’m still enjoying 5v4g with the amps with new components. didn’t have an issue with my 5D3 which has new filter caps either.
one of my 5V4G tubes shows very low B+. the 60hz hum came from it I believe
there are more and better info for 5vg and 5y3 rectifiers on the gearpage.net
I hook up tweed champ, deluxe, and m-track 2×2 together while jamming with youtube. 5v4g sounds still alive with this stereo and digital setup to me. but, m-track 2×2 is cheap and sharing the one single full bandwidth with usb and instrument at the same time. it sounds good while using only one of them. it sucks when the knob is at the center.
it’s the knob on m-track 2×2. don’t buy it if you want to use your guitar amps as monitor speakers while playing guitar through the direct input. maybe I’m just doing this wrong.
it’s a ’59 fender tweed champ with 8″ stock jensen speaker. I’ve learned more than a few things from this amp. mostly about the tone. and it forces me to play more than before I got this small tweed amp.
I’m using 5y3 rectifier for the original setup along with 5v4g for more clean headroom. and watching that huge rectifier from the back side. 5v4g and Bendix 5y3 look beautiful at night.
5F1 breaks up early and it’s the character of this amp. 5v4g makes 5F1 sounds a bit like tweed deluxe. but, it’s still tweed champ of course. and, I recently noticed 5f1 with 5v4g is more vulnerable to 60hz hum. so, I came back to the stock 5y3
this wide panel tweed deluxe 5d3 came to me with weber 12a125a speaker a few months ago. it was a very good combo and the price was fair with the new skin. but, I couldn’t stand the blue color of 12a125a. everything else was good to me and my friends.
I’ve tried a like new ’51 p12r without bell, re-coned ’53 p12r came out ’54 5C3, black ’61 p12n, and this ’51 p12q.
p12q is known as one of the original speakers for fender tweed deluxe. but didn’t have a chance to play with p12q before.
p12q breaks up early like p12r. it was my first question while I was searching this speaker. and the question has solved.
I was obsessed with vintage jensen speakers a while ago. especially with p12n. but it didn’t work well with 5d3 because of the breakup point. or the family and the neighbors.
then p12q came into my mind. the sound was great like p12n even at the lower volume. and breaks up early enough like p12r in my imaginary world before I actually got this speaker. and it came true. I love this setup and won’t change the speaker again.
I keep checking out the the leather handles since I had some trouble with fender reissue.
the humped handle in the picture came from this company, Industrial Amps it looks very close to the original ones on fender tweed amps. but, the original seemed to have 3 layers.
[udpate] it was 30 something dollars when I found it. and it’s now almost $50.
this original leather handle came with a narrow panel tweed champ. I see 4 layers from this side.
the dimensions are like this
overall length 9″ (23cm)
handle mount center to center 7″ (17.8cm)
slot to slot (inside) 6″ (15cm)
and, I’m using this to protect my leather stuff. belts, shoes, and for this old handle as well.
기타 코드를 왼쪽 리이슈와 오른쪽 오리지날에 옮겨 연결하면서 연주합니다.
소리 성향은 비슷하지만 앰프 주인이 말한 것처럼 리이슈는 담요를 한장 덮은 것 같이 답답합니다. 둘 다 NOS 튜브를 사용했구요. 스피커가 아직 길들지 않은 차이를 감안해도 비슷한 톤에 아주 다른 느낌입니다.
