Allied 435

I have a few questions about my fav receiver. an Allied 435...I believe it is a rebadged Pioneer SX-440...Is the Ground (safety ground) on the back of the receiver, of any importance? Does it protect anything? I have never used it before, do I need to? also the unit has switchable power requirements, users manual says it ships set at 240V...I have been running the unit for 4 years with no real problems..other than my surge protector it was running on just died, it was like the receiver killed the surge protector???..also the plug is only a 2 prong plug..and I swear there is distortion if the plug is put in the socket upside down..maybe it's just me...Is there anything I need to know, or just keep using it as is? I was thinking of trying it without a surge protector too..IDK? any thoughts? Thanks.J.

The plug is not polarized in old gear, so it's common to have hum issues solved by flipping the plug in the socket.
It's likely that if the unit is still working, the voltage is set to 110 or 120. If it was set to 240, it would probably not work right.
 
I personally don't know about rebadged pioneer stuff, but allied was actually ALLIED KNIGHT equipment.

The ground lug on the back was specifically for turntables, but you could also use it to common ground a tuner, cassette deck, etc.

I see you are in florida, so was the voltage set to 117-120 or 240? If 240, you were only getting half the voltage to run it properly at full voltage!
 
Allied 435 is a contract item built by Pioneer. It uses the same polarized speaker plugs as other Pioneer products of the era.
It was sold in Allied/RadioShack stores in the early 70's. No FTC power rating, TO-66 output transistors 10-12w actual output. As good as anything in it's price range, "in the day".
 
Thanks..Yep it's set to 120..there are no marks for anything but 120v on the switch..but all the holes for the different voltage settings are still there..I'm pretty sure it is a SX-440 with different front..I have seen both units apart, and they are the same...it's a nice sounding unit with very efficient speakers..my Bose 401s sounded pretty good with it..but my kirksaeters were awesome with it...I've been on an acoustic suspension speaker kick lately and this amp is not as good with them that's for sure..of course I don't like turning it up beyond 9'oclock position, so that may be why...ps I think the ground I'm talking about is for the radio..it's in the antennae section..again thanks.
 
I think you are talking about the ground post at the antenna connections. My Technics tuner has both 75Ω & 300Ω connections where as my 300Ω connection only has two posts for the dipole style antenna, and the 75Ω antenna connection has one for the wire (hot), and one for the ground. My Technics tuner does not have the coax jack (cable type) for the 75Ω hook-up, just the two posts.

Now, my Pioneer receiver has a cable jack 75Ω, and two posts for 300Ω, and a single ground post, and a single AM post.

The ground post is just the chassis ground, and it would be the same ground if your receiver/amplifier had the ground lug next to the phono input jacks.

BUMP because of misinformation: LTV Ling Altec Inc, April 16, 1970 "SOLD" Allied Radio Corp to Tandy for 30 million. After this point "1970" products were known as Allied Radio Shack, even later as just Radio Shack. I purchased my first stereo at an Allied Radio store, Northland Shopping Center "Ferguson Missouri" in 1967 at 13 years old after saving up all summer long. It's hardly a 70's stereo receiver if it just says "Allied', Heath kit, Olson, and Lafyette Radio were all seconds to Allied back then Allied was the largest electronics distributor period. The 435 was pre 1970 and Allied Radio Shack. I was actually employed by Tandy in the 80's and was the Audio Tech for the 'regional service' center in St. Louis Missouri, and I repaired more Allied and Radio Shack receivers then most people have ever seen in their life times .....only one thing amazes me, what people are willing to pay today for stuff we discouraged people not to repair yesterday, simply because they would be better off ...as far as I'm concerned there is only one Allied or Realistic that was built correctly, the STA-2280. Knight was just a brand name Allied used on products.... another misnomer in the thread. The STA-78 is one such model. Brand names and manufacturer alliances have nothing to do with good sound, so what if Pioneer made it? Pioneer isn't that great and Toshiba and Marantz engineers designed and configured far better performing output circuits based on Toshiba output transistors, top hats ....but the pre-stages are where they cut cost the most using sub-standard quality parts because American made resistors and capacitors were superior to Asian productions, and costly
It's important because misinformation sucks the truth out of life

Do you still work on stereos?
