    It seems yours is way much brighter than mine.
    I guess I may have to change the paper filter on mine.



    BTW, does anyone know whether there are other differences between the Marantz 2226B and 2226BL besides the long wave radio?
    I heard that the BL is very rare.

    The LEDs are pretty bright regardless of color :) All my bulbs were burned out so I do not have a reference point as to "how much brighter vs the lamps"

    I updated the lights to LED on a 2252 I sold some time ago. I sampled both the blue and white LEDs, but there wasn't a big difference in color. The blue LEDs had a slightly deeper blue appearance, but nothing earth-shattering. BTW, both LED types were distinctly brighter than the stock lights.

    Where did you guys bought the LEDs from?
    Can you recommend an online shop?

    I like warm white LED if going that route. Closest to the stock lamp color if you like the stock look. Anywhere in the 2500-3000K range for color temperature will get you reasonably close to standard lamp coloring. The higher the number the more towards blue it gets.

    I guess I won't be putting LEDs in my Marantz.
    Bobs Vintage Electronics doesn't ship to my country and Parts Express charges US$ 4.96 for the LEDs and US$ 99.29 for the shipping.

    If anyone knows of vendors that ship to Eastern Europe or at least to UK, please let me know.

    I do like the color of the front panel with the original light bulbs.
    But unfortunately I can't find a vendor that ships to my country at all or at a reasonable price.

    While is not clear where are you from, try www.ebay.co.uk, you'll find some vendors for all UE. Just search for '' Marantz Lamp Kit"

    +1 on Hipocrates suggestion. A few vendors on eBay.uk from Germany, Bulgaria, Belgium, Netherlands...you shouldn't have a problem finding what you need.

    A few more questions:

    I checked some electronic component shops online and some of them as for Voltage Rating AC and Voltage Rating DC but the Marantz Service Manual doesn't specify that.
    When the manual says, for example: "100uF 16V" how do I know if thats AC or DC?

    Someone said that I can put capacitors of a voltage greater than the ones specified in the parts list.
    How higher can that be?
    For example if the list says 100uF 16V, is it ok to put one that is 100V, for example?

    The uF on the new cap needs to match the original cap, but the voltage can be equal or above the original cap's rating. For your example, the new cap being 100uF/100v to replace a 100uF/16v cap would be fine to use. I guess the only thing to worry about here is the physical size of the cap. Will the new one fit in the place of the old one?

    Original caps will be rated in DC. Caps almost always are unless specifically marked otherwise.


    I might replace a 16v cap with a 25 or 35v cap but going to 100v is probably not needed and it would likely cost more. Honestly unless you've got some reason to, the original voltage capacitor will be fine. Sometimes it just doesn't exist and you have to change it though.

    The main cap I go to a larger voltage with is the filter cap, so I can match the diameter of the original cap. This way the original mounting hardware can still be used.

    that would constitute a reason to bump the voltage. I've done it for the same reason. Sometimes its voltage and value, and you still end up with this little half-height cute as button cap in there.

    Thank you, gentlemen!

    So voltages are in DC.
    Voltages can be higher but no need to go up too much unless its has a size problem like a bracket.
    Values can't be different.

    Got it.
    Thank you!
