A friend of mine (Reb A.) sent me the following information a short while ago, about minyonim where they wear tefillin on chol hamoed in Eretz Yisroel bifarhesia.
“There is one in Katamon by the Erlauer Rav (that one has a chassidish taste to it). I travel there on the 1st day Chol HaMoed. There is another one near Belz in the Minchas Yitzchak neighborhood, called Kehillas Vien. It is an Oberlander minyan, according to Minhag Pressburg. I go there for the other days of Chol HaMoed.”
