@@mikeblues4720 you will need a 12” 4 ohm speaker that’s at least 90 watts

@pontiacpete thanks friend!

@@nicholascollins6488 my test bed is either one 15” peavey black widow or one high wattage 12” speaker either a JBL or EV. I can’t remember which one was hooked up at the time.

@@pontiacpetewas passive or active?

@@nicholascollins6488 do mean a powered speaker ? No it’s not a powered speaker.

@@carnovector6396 No that’s how these sound..nice huh?

​@@pontiacpete yeah that sounds great lol thanks for the demo

@@diegooland1261 I bet that’s not an easy repair. Could be one of the many transistors that are hissy or resistor

@@pontiacpete oh, ok thank you.

@ first think is to make sure you pots and jacks are clean

@@Firebird1964 it’s not my amp, but it I believe the owner is selling it

@@kevisauceda that doesn’t sound normal. I would expect a delay but not one that varies between 30 sec and 3

Underpowered in a medium room and up. I’ve used the 600b professionally for 30 years now. I use it as a preamp for vocals and acoustic guitar. The reverb tank is exceptional. These are also great monitor amps. But if your running a band through it, you will be underpowered and limited with only six channels.

@@frankstephenson1746 used 2 of those with my popular cover bsnd in Allentown, Pa . And played some big places in Pennsylvania; New Jersey, and Delaware.plenty of volume and never a problem in "Straight Up" bsnd from Allentown.

No Bluetooth

This one is actually mine and I adore it to this day. Perfect amp for a home/studio scenario

I’m an amp repair man and I made this video to demonstrate that the amp is working. I’m playing a fender Strat directly into the amp, no effects at all. Maybe you hear the 4ths with the distortion. In my opinion this is not a great sounding amp. I don’t understand why it’s getting all the views it has gotten, considering some of the other great amps that I demo on my KZbin channel. Thanks for listening!

​@@pontiacpetehi! Thanks for your video. Which amp would you recommend to a Stratocaster? I love the Steve Ray sound. Any good amp under 500 dollars? Thanks for you reply!

@@Jakopine1 the ampeg g112 is a nice inexpensive solid state amp that sounds great. Thanks for looking!

@@Jakopine1 Look for a used Blues Deluxe

What amp would you suggest to get a joe walsh kind of tone, one thats under a 1200 bucks

I agree that your twin is really loud, they all are. Great amps! The 135 does, however have a very large power transformer and the high voltage on them is closer to or above 500vdc, and it’s a good idea to use 5881s and not modern production 6L6s. They can’t handle it. The old US made 6L6s can but they are pricey. Your 74 twin makes about 460vdc. The 135 has a bit more clean head room and would most likely have more output power. Also, it is called ultra linear because of the output transformer. These output transformers have extra windings to provide the screen voltage to the power tubes. Lots of times you see this in Hifi output transformers. Giving it a cleaner sound. Anyway your amp is still freaking loud when working properly, putting out 90 or more watts rms. Who really needs more than that. Thanks for looking,!!

Thanks for the informative information!

I don’t remember which cab I was plugged into. It was either the 4 ohm cab with a black widow 15” or the 8 ohm cab with two 12” speakers, unknown brand, that have since blown.

one of the baddest player jim marshall ever had to put up with

Who is Colleen? I know I serviced it

@@pontiacpete She made a video about one of those amps. It was great. kzbin.info/www/bejne/rYuohYKIfs2ff9ksi=ri0x5uGIZQ7qUjY1

Did you check and see if the springs are connected?

@@pontiacpete no I haven't opened it up yet but the reverb does work. The wash is long like the one in this video, mine is really short and sounds like the spring bouncing. If that makes sense lol

I don’t think I ever was able to get the complete schematic. Since the power amp section is solid state I would guess 4 ohms

@@pontiacpete thanks for the info

No we lost the drummer last fall

This cabinet is from a fender DSP princeton. I just built the tube circuit

Standby is most important for turn on, it allows the heaters to heat the tube before the high voltage hits the plates. Turning the amp off, doesn’t matter how you do it.

No. It was a repair
